A day ago I have installed Mono 2.10 ( for C# 4 support ). Since then server was randomly restarting whenever there is C# app running with no error messages or anything.

Some lines in log files are overlapping I guess because it did not finish writing that line before server restarted.

If you will need more information, tell me. Thank you.
- Installed kernel 2.6.32 from Debian repository. Problem still was not fixed.
- Memtest did not report anything bad, tests passed.
- Updated to official testing Debian kernel 3.2 seemed to fix problem. ( so far almost 24 hours up time, allot better than was before at least )
