I faced this issue with Visual Studio (VS) 2010. It would be appreciated if anyone knows any possible causes, or some kind of way to identify whats causing the problem. Nothing seems to make this issue go away. I've tried turning off compiler optimizations and several microsoft hot-fixes. net 2.0, 3.5, and 4.0 and on multiple servers and the problem still eventually occurs. I have tried debugging this in VS2008 & VS2010 using. The only outside resources this application uses is socket connections and SQL database connections. It uses no 3rd party software or other APIs. Its constantly running code to maintain the environment even if the clients are not doing anything. I dont think its leaking because the memory usage stays relatively constant the entire time the application is running. It consumes quite a bit of memory but I do not see it leaking. The server runs a virtual 'environment' for the clients where they can interact with each other and the environment. Clients connect to the server via socket.

Its a multi-threaded server application written in entirely in C#.

In a nutshell this is what the application does:

When this happens all threads show terminated and there is no debugging information available. This may be a bug in the CLR or.' something about PInvoke or other non relevant info. Sometimes it will stop in a seemingly random spot and throw the above error, other times the entire application stops and I get a screen with an error that says something along the lines of 'There was a fatal error in. The application will run anywhere from 12-48 hours before throwing the error. I cannot really post code because this error seems to get thrown in any random area of the application. This is often an indication that other memory is corrupt. I'm hoping someone can enlighten me as to what could possibly be causing this error:Īttempted to read or write protected memory.
