Server Crashes

Hi all,

 

I just wanted to address a server crash both our 2Fort and High Tower servers experience when performing 2 - 3 map changes over the span of 3 - 5 days. The server crashes as soon as the map changes and there is no engine error before the crash. Here is the stack trace:

 

Program terminated with signal SIGABRT, Aborted.

This is a very odd crash considering it's calling Linux functions. The only entries that refer to the Source Engine itself is towards the end of the stack trace (e.g. "CBlockingUDPSocket:WaitForMessage(float)"). I might try to learn more about GDB and how to inspect the core dump file. Specifically, I'm curious about how to retrieve the float parameter's value in the CBlockingUDPSocket:WaitForMessage function. I plan to open the engine_srv.so file in IDA and look for this function to see if I can gain more information on what it exactly does.

 

Thank you!
