WinDBG Help - Access Violation in Managed Code

I have a server application written in C#. The application uses no 3rd party software or DLLs, its all managed. Clients connect to the server via socket.

Eventually, the application fails due to an Access Violation exception. Sometimes it will run for minutes, hours, or days without the error occurring. I believe the error is occurring when a new client connects but I'm not sure. I've managed to get WinDBG to break when an access violation occurs but I'm not very savy with it.

Heres what I have from WinDBG. I'm just including the output from several commands... Please let me know if there is anything else I should be getting.

(dc8.f94): Break instruction exception - code 80000003 (first chance)

First chance exceptions are reported before any exception handling.
