What mod_python are you trying to use to test it out? Are you trying to follow the simple mptest.py example, or have you gone direct to trying to use some complicated example which loads in all manner of extra Python modules? A few things to try are as follows. 1. Use procedure documented at: http://www.dscpl.com.au/articles/modpython-001.html Let us know how far you get with this or whether it dies from the outset. 2. Grab latest version of mod_python from subversion repository. It includes fixes for a few obscure problems that might conceivably cause core dumps. https://svn.apache.org/repos/asf/httpd/mod_python/trunk/ It also includes some better logging whereby some problems are now logged whereas they weren't before and thus you had no idea what was going on. 3. Do you have multiple versions of Python installed on your system and there is any chance mod_python is loading stuff from wrong version? 4. What version of expat package do you have installed? Some version can cause core dumps. See: http://www.modpython.org/pipermail/mod_python/2004-December/017023.html 5. Having different packages using different versions of shared libraries can also be a problem. This can occur with expat, but also Berkley DB shared libraries. For examples, see: http://www.modpython.org/FAQ/faqw.py?req=show&file=faq02.013.htp About all I can think of for now. Graham
