OK, I do have a "virtual host", www.emergentgravity.org defined on this system.In /etc/httpd/conf/vhosts.d/00_default_vhosts.conf I have ---------------------------------------- NameVirtualHost *:80
<VirtualHost *:80>
ServerName www.theory.physics.ubc.ca
ServerAlias theory.physics.ubc.ca
DocumentRoot /usr/local/http/htdocs
</VirtualHost>
<VirtualHost *:80>
ServerName www.emergentgravity.org
ServerAlias emergentgravity.org
DocumentRoot /usr/local/http/htdocs/emergent/drupal.new
</VirtualHost>
-------------------------------------------
This is the whole of that file.
This is supposed to be so that a www.emergentgravity.org address goes to its
drupal document root, and such that anything coming in to
www.theory.physics.ubc.ca comes in to /usr/local/http/htdocs.
If you suspect I have no idea what I am doing in setting this up, you are
correct. Have I managed to stick in a feedback loop in here?
Can you interrupt one of the truly hosed processes using gdb and try 'thread apply all bt'What does that do?Dumps all threads instead of just one of them.Thread 1 (Thread 0xb760f700 (LWP 20861)): #0 0xffffe424 in __kernel_vsyscall () #1 0xb77ece6b in fcntl () from /lib/i686/libpthread.so.0 #2 0xb780f832 in ??

Unfortunately Mandriva never bothered to supply the apache-debug package for this version of apache.
looks like it might be in the accept queue waiting on the MutexFile to unblock this one (and is probably a healthy process). If you are running prefork we would encourage you to try the worker mpm.
Sorry, I have no idea what this sentence means. (prefork, worker mpm)
