Are you using Python as supplied by Apple or from elsewhere? Since the problem is due to daemon process crashing, the quickest thing to do is work out where. That may then save round about path of suggesting all the possibilities. So, following instructions in: http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Debugging_Crashes_With_GDB for using gdb to capture stack trace for crash of daemon mode process. That is, use default of single process as provided by WSGIDaemonProcess, use logs to identify the process ID easily. Need to set LogLevel to 'info' in Apache to get that information. Attach gdb to that process ID and then trigger request. Use gdb to get stack trace for all threads. Various of the reasons for crashes re described in: http://code.google.com/p/modwsgi/wiki/ApplicationIssues It is a bit odd that you would get it for empty Django installation. Although that depends a bit on which Python installation is being used. Graham -- You received this message because you are subscribed to the Google Groups "modwsgi" group.
