Mod_proxy Slow After a Week

[Robert Gabriel <ephemeric@xxxxxxxxx>]

Hello all,

We have:

Apache 2.2.3

CentOS 5.5 x86_64

Splunk 5.0.2

I only know the basics but Apache has been serving us very well with the below config

and only after about a week did pages refresh very slowly, up to a minute to reload

sometimes.

I tailed both httpd and splunkd logs and saw a consistent delay of 30s between proxy

and origin server (both on same host) along with plenty of 304s, followed by what

appeared to be some timeout and then slowly the 200s started coming back in.

A restart of httpd cleared up the issue.

I'm lost, please help.

Could this be a caching problem?

Thank you.
