Hello,
I’m searching for a way to determine why apache would present/return a 503 Service Unavailable. I cannot seem to find a way to log this other than the fact that it occurred. There is no information in the error_log nor in /var/log/message nor in any of the access_logs dealing with any of the vhosts when this occurs.
We receive this error on about 1% of all requests. So far this month, we have 2,274,314 unique visitors comprising of 82,602,703 hits (according to awstats), so 1% is a lot!
How can I determine the “reason” behind the 503? I tried looking at apache source to see where “return error_503” may be but that is a daunting task.
We are running PHP with the suPhpexec module, if that matters. All mod_proxy* modules are disabled. We are running 2.2.14 on RHEL5.4.
Thanks in advance!
