Apache segfaults with Zope/Plone. I'm not sure why.

I'm running Plone. I want to use Apache to access Plone, as the documentation recommends. But this is what happens:

Sites that use mod_rewrite, mostly Wordpress sites, work without a problem.
Zope and plone work fine, including with the VirtualHostMonster used by Apache. No problem.

BUT, using Plone THROUGH Apache, gives this in the error_log:

Code:

[notice] child pid 9903 exit signal Segmentation fault (11)

Obviously, the pid changes every time.

The mod_rewrite instructions, as indicated in the Zope and Plone documentations, are:

Code:

RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/http/%{SERVER_NAME}:80/sitename/VirtualHostRoot/$1 [L,P]

Removing the [P] flag does not help.

It seems that the problem is cause by a module. Is it mod_rewrite? In which case why does Wordpress work? It is mod_proxy? In that case, why does removing the proxy flag not work? Is there a way to find out more?

Thank you to anyone who can help.

The above %{SERVER_NAME}:80 in the RewriteRule is not correct. You should replace it with your server name and (maybe) escape the ":" character:

Code:

RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/http/www.domain.com\:80/sitename/VirtualHostRoot/$1 [L,P]

Hope that helps

The people on the #httpd irc chat room gave me instructions for a more thorough debug. I tried debugging and it started working again. I'm not sure why. I think that there had been an update that created a conflict in the binaries and that the /etc/init.d/httpd reload|restart commands did not fully reload Apache, so the conflict remained. With a full stop and then a new start, all got reloaded worked. Hot dog! And I spent days on it!
