MVC3 Out Of Memory Exception - asp.net-mvc-3

After deploying an MVC3 application that has Telerik Extensions menu, I have noted there are times it throws an OutOfMemoryException and after that the application freezes and no user is able to use the application until after about an hour or so.
I managed to trace the errors from the windows event log and the following is a stack trace of one of the errors extracted from the event log
Exception information:
Exception type: OutOfMemoryException
Exception message: Exception of type 'System.OutOfMemoryException' was thrown.

}
</div>
</div>
</nav>
The application is running on a Windows 2003 SP2 which has 4Gb of memory and the users are using Mozilla Firefox to access the system.
I have googled and searched in Telerik forums and SOF and found no answers or similar users who could have had a similar problem.
What could be causing this error and how can I go about in resolving it?

Resolved the problem by monitoring performance and memory usage on the server.
I realized IIS was competing for memory with SQL Server and the memory was not
being recycled frequently and this was what was causing the problem
Following recommendations from IIS 6 Administration, I performed the following:
Set application pool to recycle after a preset number of requests
Set times to recycle worker processes during low activity times
Set a cap on the amount of virtual and physical memory to be used by
the application
Performing the above has totally eliminated the problem.

Strange umbraco media cache error happening randomly since 1 January

We are running umbraco 7.15.1
Sudenly we started getting cache error on our logo file and it is happenning randomly. On first occaccion it caused all our website down.
Despite it is the main image of the site - the logo - it does happen only in selected random places. For example the logo displays fine on the website header but fails in an email template or schema snippet.
When it first happened we did update dll on the server and the issue seemed to have been gone but it suddeny happened again yesterday - in a totally different place - in a scheduled task in this case.
Does anybody knows why this may be happening or how to permanently stop it happening again?
This is the example of the related stacktrace:

get_Logo()
is a get accessor of Logo property.
The property sits under Settings doc type in our umbraco. The namespace for this is MySite.PublishedModels. Logo is of media picket type.
It simply can't get the Logo media file for some reason.

NullReferenceException in MvcSiteMapProvider at production

The problem is I regularly get the error at the production site (ASP.NET MVC 3) but can't reproduce this error locally.
The text of exception is:

I have no such errors locally. Here is where I invoke MvcSiteMap().SiteMapPath() method:
May be somebody had the same problem before. If so please share your solution.
Thanks in advance.
This won't answer your question directly, but may help you on your path to debugging the issue, seeing as it happens only in production and not in dev/debug.
Consider replacing your line:
#Html.MvcSiteMap().SiteMapPath()
With something like:
#SafeBreadCrumb()
#helper SafeBreadCrumb() {
MvcHtmlString output;
try
{
output = Html.MvcSiteMap().SiteMapPath();
}
catch (Exception e)
{
output = new MvcHtmlString(e.Message);
}
<text>#output</text>
}
Feels a little dirty, but it's easier than grabbing the source of MvcSiteMapProvider and sticking in some logging! If it happened in debug, you wouldn't need to try this. Plus it's just a view change, so won't need a recompile.

NuGet Gallery and EntityFramework throws Failed to open provider error

We have a weird situation going on here. We have setup a local installation of NuGet gallery (the same code that powers http://Nuget.org). The IIS and the DB are on the same box. The IIS App pool has been configured to run under a domain user who is the local admin on the box as well and has the "right to logon as a service" rights. Now when someone (after succesfully logging in) tries and upload a package, the upload package business takes ages and eventually throws up the "The underlying provider failed to open" error

Interestingly if I switch IIS App Pool to run under the built in "LocalSystem" account all these problems goes away. The domain user we want to use has been temporarily setup as the database owner for NuGetGallery database but it isn't helping.
Can anyone suggest what setting/configuration we might be missing here?
This was due to ambient transactions going on within the code. The code relied on TransactionScope classes to manage various transactions which were getting in a jam when they got nested. Things turned particularly bad if someone tried uploading a package which was more than around 10MB in size. Once we tweaked the MSDTC on the boxes the application started behaving slightly properly. However it was still intermittently getting deadlocked within its own transactions so for now we have decided to remove transactions from the package upload bit.
For anyone else who gets into this problem I would recommend either of these two
Comment out any reference to TransactionScope in
Services\PackageService.cs (method CreatePackage, line 48)
using (var tx = new TransactionScope())
{
using (var stream = nugetPackage.GetStream())
{
UpdateIsLatest(packageRegistration);
packageRegistrationRepo.CommitChanges();
packageFileSvc.SavePackageFile(package, stream);
tx.Complete();
}
}
And in Controller\PackageController.cs method VerifyPackage(bool? Listed) line 501
using (var tx = new TransactionScope())
{
package = packageSvc.CreatePackage(nugetPackage, currentUser);
packageSvc.PublishPackage(package.PackageRegistration.Id, package.Version);
if (listed.HasValue && listed.Value == false)
packageSvc.MarkPackageUnlisted(package);
uploadFileSvc.DeleteUploadFile(currentUser.Key);
tx.Complete();
}
2 Uncomment those lines and follow the approach mentioned here http://blogs.msdn.com/b/dbrowne/archive/2010/05/21/using-new-transactionscope-considered-harmful.aspx
Basically create a transactionscope which can work well with SQL Server. Create a new class in the InfraStructureFolder, call it TranscationUtils and copy the code in there. Then the using blocks would look like
using (var tx = new TransactionUtils.CreateTransactionScope()){
//cod here
tx.Complete();
}
However this second approach can result in another server error which again relates to the default time outs you can specify for TransactionScope. We have personally decided to go with approach 1 and comment out all TransactionScope references for now.

"Cannot create an instance of an Interface" (an MvC 3 Wizard inside Orchard CMS)

Based on the great answer at multi-step registration process issues in asp.net mvc (splitted viewmodels, single model), I used the example Darin Dimitrov provided to test out an ASP.net MVC3 wizard. It works standalone, but not inside Orchard CMS v1.3.
I am getting the following error:

I am venturing a guess that it's the controller that's causing a fuss. Here is the code:
[Themed]
public class WizardController : Controller
{
public ActionResult Index()
{
var wizard = new WizardViewModel();
wizard.Initialize();
return View(wizard);
}
[HttpPost]
public ActionResult Index([Deserialize] WizardViewModel wizard, IStepViewModel step)
{
wizard.Steps[wizard.CurrentStepIndex] = step;
if (ModelState.IsValid)
{
if (!string.IsNullOrEmpty(Request["next"]))
{
wizard.CurrentStepIndex++;
}
else if (!string.IsNullOrEmpty(Request["prev"]))
{
wizard.CurrentStepIndex--;
}
else
{
// TODO: we have finished: all the step partial
// view models have passed validation => map them
// back to the domain model and do some processing with
// the results
return Content("thanks for filling this form", "text/plain");
}
}
else if (!string.IsNullOrEmpty(Request["prev"]))
{
// Even if validation failed we allow the user to
// navigate to previous steps
wizard.CurrentStepIndex--;
}
return View(wizard);
}
}
But I am not 100% sure, and the other culprit could be the WizardViewModel:
[Serializable]
public class WizardViewModel
{
public int CurrentStepIndex { get; set; }
public IList<IStepViewModel> Steps { get; set; }
public void Initialize()
{
Steps = new IStepViewModel[]
{
new Step1ViewModel(),
new Step2ViewModel(),
new Step3ViewModel()
};
}
}
That last part is a manual insertion of the steps and alters the code originally posted (direct from author). Any help is greatly appreciated.
Apparently, the Model Binder you are using can't find the model it needs to instantiate from the supplied interface (IStepViewModel)
I am quite sure that the default ASP.NET MVC ModelBinder can't do such thing, as it would require some custom logic to choose the concrete interface implementation that should be instantiated.
Therefore, you have two solutions:
Check your sample, I think it provides a custom ModelBinder, and register it in Orchard by implementing an IModelBinderProvider
Don't ask for a IStepViewModel in the Index action:
public ActionResult Index([Deserialize] WizardViewModel wizard, IStepViewModel step)
And replace it with a concrete class.

ASP.NET MVC3 RC2 <AllowHtml()> not working

I've got my input decorated as follows.
<AllowHtml()>
<UIHint("MarkDown")>
<DisplayName("about")>
<Required(ErrorMessage:="Description is required")>
<StringLength(2048, ErrorMessage:="Description is too long")>
Public Property Description As String
My editor template looks like this
#ModelType String
<noscript><h3>Please use #Html.ActionLink("Markdown", "Markdown", "About") to style your input.</h3></noscript>
<div id="wmd-button-bar" class="wmd-panel"></div>
#Html.TextArea("", Model, 5, 10, New With {.id = "wmd-input", .class = "wmd-panel"})
<div id="wmd-preview" class="wmd-panel"></div>
<div class="clear"></div>
and when I try and intentionally submit a <script> tag, I get the YSOD
A potentially dangerous Request.Form value was detected from the client (Description="... here. <script>
var a = b;...").
My question: how do I make this work?
EDIT
Here's the controller Action Method
''# fix stack overflow code coloring
''# <AcceptVerbs(HttpVerbs.Post)>
Function Edit(ByVal user As Domain.User, ByVal id As Integer) As ActionResult
If AuthenticationHelper.RetrieveAuthUser.ID = id Then
If Not user.RegionID.HasValue Then ModelState.AddModelError("UserRegion", "Invalid region selected")
''# We only want to process the View Data if the state of theB
''# Model is valid. If it's not valid, we send the user back to
''# the View with some validation instructions. This really only
''# happens if the user has JavaScript disabled because we're also
''# using Client Side validation for a friendlier user experience.
If ModelState.IsValid Then
''# We want to update the user record before we expire and
''# re-issue the authentication cookie so that the new data
''# will be issued to the new authcookie.
UserService.UpdateUser(user)
UserService.SubmitChanges()
''#Expire the cookie and recreate it
''# when all is said and done, send the user
''# back to their profile page.
Return RedirectToAction("Details", "Users", New With {.id = id, .slug = user.UserName.ToUrlFriendlyString})
Else
Return View(user)
End If
Else
Throw New ResourceNotFoundException()

Thanks for the report. This is another manifestation of a caching bug described at http://forums.asp.net/p/1632006/4206895.aspx. The workaround steps are the same; from within Global.asax Application_Start, put this line of code:
ModelMetadataProviders.Current = new DataAnnotationsModelMetadataProvider();
This will disable the errant cache.
