When I am starting the grinder to load test a simple Web Application nothing happens and it goes to hang .
I had previously run the same scripts on different machine and it used to work.I tried to debug it by putting print statements and saw that print after GET was not coming.
Any help or suggestion welcomed ..
Well this came out to be a system issue since same setup is working on a different machine. However I figured out that by running grinder in grinder.debug.singleprocess mode and setting up -javaagent:path/grinder-dcr-agent-version.jar works on the same machine . This is strange for me as well .Hope that helps.

I'm using VS codespaces to complete the current CS50X course.
I've been getting on very well with it but have hit a snag where the Terminal doesn't seem to be loading correctly. I think i'm missing a couple of options at the top of the Terminal section - Debug and Port. I'm trying to complete the Finance section of the course which involves connecting to a development server but when i try i get the following erroe message:
{"type":"https://tools.ietf.org/html/rfc7231#section-6.5.4","title":"Not Found","status":404,"traceId":"00-76b8a3e0c4eaccf805373ec05e5ec917-dccabf0efd4cf681-00"}
I've tried to Google what might be going on but i'm very new to programming and don't understand a lot of what i'm reading!!
I did notice that the shell has failed to initiate, but again, i don't really know what that means.
I've tried re-loading the window repeatedly but still get the same situation.
Any ideas would be much appreciated!!
I am curious about the Lab of Things and i've just started to learn it.
I am studying it in the network lab of my university. We have a z-wave controller stick, 2 on/off switch, 1 dimmer receiver and 1 sensor.
To set and run the platform, i followed the instructions in this link below:
http://www.lab-of-things.com/GettingStartedLoT_Beta1.pdf
While running the source code and adding a z-wave device, I faced an annoying problem here.
After adding the z-wave driver and running the code i saw 4 different device on the dashboard, it looks like below:
I tried to install these nodes and applications but apps are not installed. I think that's why i get an error message like below when i run the platform:
I searched on the internet for this error and i found a discussion like this error but i couldn't apply the solution. In this discussion they say that the applications (alerts, sensor, lights etc.) should be compiled seperately. I tried to do it but Visual Studio still gives the same error.
Here is the link of discussion that i found on the internet:
https://labofthings.codeplex.com/discussions/476781
All answers will be appreciated.
Thank you in advance.
I solved this problem by following these instructions which are written in this link:
https://labofthings.codeplex.com/discussions/476781
" For starters, it looks from the screenshot posted on stackoverflow that you have broken configuration at this point—the access control rules (in output\configs\config\rules.xml) have a reference to module Alerts but that module is not listed in output\configs\config\modules.xml
To fix the config, 1) run reset.bat, which will reset your configuration to default; or 2) fix it manually if you think you understand the semantics.
Then, make sure that the apps you want to use are compiled. Their binaries should show up in output\binaries\pipeline\addin\homeos.hub.apps.alerts.
Then, go through the setup process again, and things should work at this point in time.
A little more on this: we have confirmed that broken configuration will occur when app binaries are not found. We will post a bug fix soon, but for now, the remedy in my original response (reset, compile, then install device) should work. Let us know if you are still seeing issues. "
I hope this would be helpful for someone.
As far as I can detect all machines are the same that excelDna is being used on.
On one specific machine I tried to use the code I have created, and ran into an issue. Logically I thought this was odd and instead tried to add a sample file that comes with the download.
So now, I am trying Errors.xll/Errors.dna that come as a sample. The same error occurrs. Therefore to me there is an issue on this specific machine.
The error I am receiving is "a problem occurred while an add-in was being initialized (InitialIntegration failed). The add-in is built with ExcelDna and is being loaded from P:\xlDna\Distribution\Errors.xll"
Has anyone encountered this? Help needed to understand why this is happening as it seems quite opaque to debug.
Hi what solved this for me was moving the xll and DNA to the users c:. Once located on the c: worked flawlessly.
Hope this helps someone else in the future.
We are using watir webdriver to test our applications. Currently I have 20 watir tests kicking off every 1 or 3 minutes on a linux server. Due to the way firefox works, we would constantly have tests fail to run because of it's locking port 7055 during launch. Tests that start at the same time would eventually time out if the port wasn't released in time.
After tons of experimenting, I seem to have been able to get around this issue by modifying this file:
gems/selenium-webdriver-2.21.1/lib/selenium/webdriver/firefox/launcher.rb
I added this bit of code near the top to assign a random locking port instead of just the default 7055. This seems to have helped a lot, only seeing the rare failure now.
Asking if there is a better way to do this or if this could introduce any problems?
### added to attempt to reduce unable to open firefox issues
if #port == 7055 then
#port += rand(2000)
puts "PORT: #{#port}"
end
Anyone else messed with this? I'm pretty new to ruby so guessing there is a far better way to script that.
Thanks for any input you can provide.
Instead of modifying the firefox launcher.rb I think you are better off incorporating some logic at each of your scripts. Something like this might help!
Have a look at the link below:

I'm having a very strange problem. I'm using dfs-datastores Pail abstraction to write data to HDFS in Java. I don't think the Pail piece is important to the problem though.
When it calls org.apache.hadoop.fs.FileSystem getFS(java.lang.String path) with a path on my local filesystem it pauses for about 2 minutes seemingly doing nothing then returns. This is on my laptop.
The weird thing is that it worked really fast when I was on the network at my office today, but now that I'm home it's doing it again. I'm running Ubuntu 10.10 64-bit with Java 1.7.
Anyone have any ideas what it's doing? What could be different between being at work and being at home?
UPDATE:
I've been stepping through code with the debugger and it seems to be having trouble in Configuration.loadResource(). It's calling that multiple times and it will take 5-10 seconds to return from that function.
UPDATE2:
I've narrowed this down a little further. The biggest hang up seems to be when it calls KerberosName.setConfiguration(). Which would explain why it runs fast at work since the Active Directory acts as a Kerberos server. I don't have one here at home, so it can't find one. Now they question is why in the world it's trying to load the Java Kerberos stuff.
I found a solution (or at least a work around). I installed the krb5-kdc package and now my little program runs fast without any unexplained pauses. After this I removed krb5-kdc, tested and it was still running fast. I removed /etc/krb5.conf and it started doing the pause again. It looks like using the Hadoop library on Ubuntu (at least) requires a /etc/krb5.conf file.
Maybe this will help someone else.
