Is it definitely coming from mod_python code? Does it generate any sort
of Python stack trace in the Apache error log or any other message? If
using mod_python 3.2.8, pretty well all of the places in mod_python
which generate a 500 error should log a stack trace or some other
informative message as to why the 500 error was generated. Also, when
you say crash, do you mean the 500 error, or an actual Apache crash
due to a segmentation fault or something?
