One quick note if under Linux and suspect SELinux interactions.... There have been cases where the SELinux (advanced security enhancements) can cause Apache to segfault - on purpose. But SELinux has a lot of benefits too, so rather than just flat-out disable it, you should first put it into so-called "permissive" mode. First, see if SELinux is actually running. As the root user, # sestatus and see if you get output that says both SELinux status: enabled Current mode: enforcing If you don't see that, then SELinux is not your problem. But if it is enabled AND enforcing, then you can temporarily put it into permissive mode by using: # setenforce 0 While in permissive mode, the SELinux kernel will continue auditing actions that it would normally have taken, but will not actually prevent any attempted accesses (and thereby will not cause and seg faults). Those audit messages, if they occur, will typically show up in your syslog output (under /var/log/messages), though that may depend on which Linux distro you're using. If putting it in permissive mode suddenly fixes your problem, then please let us know and we can try to figure out what's going on and if there's an easier and better solution than having to completely disable SELinux. If you still see crashes even when in permissive mode, then SELinux was not your problem (or at least it's not the only problem). Use "setenforce 1" to re-enable enforcing mode. You can go back and forth between enforcing and permissive modes at will. However once you disable SELinux completely, it is much more complicated and involved to correctly re-enable it again. -- Deron Meranda http://deron.meranda.us/ -- You received this message because you are subscribed to the Google Groups "modwsgi" group.
