Hi,
I have Apache 2.0.53 running on linux ( 2.4.19 kernel ). 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:
<IfModule worker.c>
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?
