Server crashes

[pkrall520]

After running CodeBrag for sometime, I find that the server crashes. I have not been able to check the duration between it crashing, but it seems to happen about once a month. We are running it with 21 SVN and GIT repos.

Hello. This issue just happened. It seems like it too about 18 days to crash.

Is there any advanced type of logging I can do to figure out where that Null Pointer comes from?
