Interesting bug. When I try to subscribe to magento newsletter, I end you getting an internal server error 500. However on refresh via the url, it gives me the thank you for subscribing and adds to the database too!
Can anyone shed some light into this or faced similar problems?
Julian
PS: Thank you in advance
Please see your web servers log for errors. Usually the servers logs the occured php error which results in the 500 internal server error.
Many things could force this error. For example max_execution_time or memory overflow.

.net application starts giving error http 400(bad request) when 200 concurrent users are loaded.
And while running script, when application is browsed manually, could able to see same errors. This basically rules out, its not client issue.
So What is causing this error?
Kindly help
We don't know but it sounds like an application bug in any case because HTTP status codes 4xx are client errors and given it occurs only under the load the application should respond with 5xx server error codes
You need to inspect your application/webserver/loadbalancer logs as most probably the cause can be figured out from them.
Also it would be a good idea to check whether your application has enough headroom to operate in terms of CPU, RAM, etc as the errors could be caused by simple lack of resources. You can use i.e. JMeter PerfMon Plugin for this

I know I am too late to answer. But I have noticed that this usually gets solved if you clear your cookies.
Calling https://www.googleapis.com/appsmarket/v2/licenseNotification/[myAppId] has suddenly started returning 500 Backend Error every time.
500 error is a generic message, given when no more specific message is suitable. There are a number of causes for a 500 Internal Server Error to display in a web browser.
With any error message, particularly one as broad as the 500 Internal Server Error, you will first want to check your error logs for your server. These logs can provide valuable context related to any code failures or other potential causes of a site failure.
As stated in the answer in this SO question.
In general, every Backend error should be handled with an exponential retry, as
there might be service problems.
If the error still persists after let's say 10 hours then you should
contact the support in order to provide you 1:1 help to your problem.
After sending a POST request from the administrator module creation area, I receive a 'connection reset' error. The content is quite a large amount. Any ideas why this could be?
That sounds like a too much data or too much time problem. The related PHP settings are post_max_size or max_execution_time. You have to check yourself or ask your hosting provider.
Usually in the server log you can find the exact cause for the problem.
I've got my Web API interface working fine but after a fairly short period, like around 5 minutes, it gives a 500 Internal Server Error on the first call and then works fine again until it times out. I'm not getting any additional information on the error message and there's nothing going to the logs. I don't have the issue on my development machine, just on the live server. Any ideas what might be causing this? How can I get additional error information on a live server?
The simple answer to this was set Custom Errors Off within the Web.config file. That gave a very useful error that made it easy to track down the problem.
