That other case didn't involve PHP, so not really related if disabling PHP solves the problem. There are some known conflicts between PHP, Python and Apache in respect of shared libraries, but I couldn't actually find the example I thought I had seen of urllib2 causing an issue. On Python 2.5, if I calculate what new modules urllib2 imports I get: mimetools <module 'mimetools' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/mimetools.pyc'> cStringIO <module 'cStringIO' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/cStringIO.so'> _bisect <module '_bisect' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_bisect.so'> _socket <module '_socket' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_socket.so'> sre_compile <module 'sre_compile' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/sre_compile.pyc'> _sha512 <module '_sha512' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_sha512.so'> _hashlib <module '_hashlib' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_hashlib.so'> _sre <module '_sre' (built-in)> _ssl <module '_ssl' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_ssl.so'> httplib <module 'httplib' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/httplib.pyc'> rfc822 <module 'rfc822' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/rfc822.pyc'> urlparse <module 'urlparse' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/urlparse.pyc'> _random <module '_random' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_random.so'> _sha256 <module '_sha256' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_sha256.so'> tempfile <module 'tempfile' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/tempfile.pyc'> base64 <module 'base64' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/base64.pyc'> binascii <module 'binascii' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/binascii.so'> urllib <module 'urllib' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/urllib.pyc'> sre_constants <module 'sre_constants' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/sre_constants.pyc'> re <module 're' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/re.pyc'> _struct <module '_struct' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/_struct.so'> math <module 'math' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/math.so'> fcntl <module 'fcntl' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/fcntl.so'> string <module 'string' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/string.pyc'> urllib2 <module 'urllib2' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/urllib2.pyc'> struct <module 'struct' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/struct.pyc'> hashlib <module 'hashlib' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/hashlib.pyc'> socket <module 'socket' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/socket.pyc'> thread <module 'thread' (built-in)> bisect <module 'bisect' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/bisect.pyc'> strop <module 'strop' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/strop.so'> random <module 'random' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/random.pyc'> time <module 'time' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/time.so'> sre_parse <module 'sre_parse' from '/usr/local/python-2.5.2/frameworks/Python.framework/Versions/2.5/lib/python2.5/sre_parse.pyc'> The important ones to look at here are those from lib-dynload as they are the C extension modules. Of note, the SSL and crypto modules get imported and this may a cause of the problems as conflicts between SSL and crypto libraries has been a problem before. http://code.google.com/p/modwsgi/wiki/ApplicationIssues#SSL_Shared_Library_Conflicts http://code.google.com/p/modwsgi/wiki/ApplicationIssues#Python_MD5_Hash_Module_Conflict The hash module issue though was specific to Debian Python 2.4, where they had broken it, thus wouldn't have thought it was cause a problem again, unless it has again been broken somehow. You could perhaps narrow it down in respect of hash module problem, by reenabling PHP but ensuring that PHP mhash module has been disabled. But then, Python md5 module shouldn't even be getting used with Python 2.5 as has been superseded by hashlib. If there are SSL problems as described though, it can still attempt to load md5 module, but by rights that shouldn't exist and would only be able to be found if somehow you have an ungodly mixing of your Python 2.4 and 2.5 installations. Just to rule this out, you might indicate whether you have both Python 2.4 and 2.5 installed and whether you have fiddled with WSGIPythonHome, WSGIPythonPath directives or python-path option to WSGIDaemonProcess. That all said, probably the easiest way of working out why it crashes, if due to a shared library conflict, is to find out exactly where it crashes, by using procedure detailed in: http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Debugging_Crashes_With_GDB Use Apache single process mode, or attaching to daemon by PID, whatever is more convenient. Make request and then use 'thread apply all bt' to work out what threads were doing at point crash occurs.
