I have observed that after running for 2 days OR after load testing (around 200 simultaneous connections for 30 minutes), it hangs, i.e. client is able to connect to server socket but no http response comes back. It is using SSL, so SSL cert warning comes but no further processing is done. Following is MPM conf: ThreadLimit 150 ServerLimit 100 ThreadsPerChild 30 MaxClients 3000 StartServers 2 #MinSpareThreads 20 #MaxSpareThreads 100 MinSpareThreads 20 MaxSpareThreads 100 MaxRequestsPerChild 2000 At this moment, the apache processes also not get reduced. It always remain the same (around 400) till i restart apache. strace on httpd processes show that they are blocked in write to some pipe. There are no segmentation faults or nasty errors in error logs. Situation does not resolve by graceful restart too. Any hint, how i should resolve this issue?
