I suspected a general memory issue first, so I changed the default worker setup to (following http://blog.zakame.net/tips/apache2-worker-lowmem): <IfModule mpm_worker_module> MaxClients 10 MinSpareThreads 3 MaxSpareThreads 7 ThreadsPerChild 3 MaxRequestsPerChild 200 </IfModule> With mod_wsgi and LogLevel debug, I get: [Sat Jan 30 08:58:06 2010] [debug] proxy_util.c(1854): proxy: grabbed scoreboard slot 0 in child 5674 for worker proxy:reverse [Sat Jan 30 08:58:06 2010] [debug] proxy_util.c(1950): proxy: initialized worker 0 in child 5674 for (*) min=0 max=25 smax=25 [Sat Jan 30 08:58:06 2010] [notice] Apache/2.2.3 (CentOS) configured -- resuming normal operations [Sat Jan 30 08:58:06 2010] [info] Server built: Nov 12 2009 18:46:18 [Sat Jan 30 08:58:06 2010] [debug] worker.c(1740): AcceptMutex: sysvsem (default: sysvsem) [Sat Jan 30 08:58:06 2010] [alert] (12)Cannot allocate memory: apr_thread_create: unable to create worker thread [Sat Jan 30 08:58:08 2010] [alert] No active workers found...
