I have a long-running python/CherryPy Web App server process that I am running on Mac OS X 10.8.5. Python 2.7.2 running in 32-bit mode (for now, I have the code in place to change over to 64 bit, but need to schedule the downtime to do it). On the 6th of this month, during normal operation from what I can tell, and after around 33 days of trouble-free uptime, the python process crashed with a SIGABRT. I restarted the process, and everything looked good again until yesterday, when it again crashed with a SIGABRT. The crash dump the system gave me doesn't tell me much, other than that it looks like python is calling some C function when it crashes.
Can anyone give me some hints as to how to track down the cause of this crash? It's especially problematic since I can't mess with the live server for testing, and it is quite a while between crashes, making it difficult, if not impossible, to reproduce in testing.
