Ruby app hangs when no new requests come in to http server

Hello,

I am new to ruby on rails so pardon any ignorance, indiscretions, etc. I have inherited the administration of a RoR web app that runs under mongrel. My problem is that as long as there are http requests coming in the application stays responsive indefinitely, however, when no reguests come in it appears as though the app hangs. The browser times out with:

Proxy Error

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /.

Reason: Error reading from remote server

Apache/2.0.52 (Red Hat) Server at 204.xx.xx.xx Port 80

the funny thing is that if I request an image from the /images directory it serves the image up fine. I am running:

RHEL5 x64 Apache/2.0.52 Mongrel 1.1.3 Ruby 1.8.5

Has anyone seen this before?

Check your production log if there's any error.

I think your server is rebooted. try this:

[~] crontab -e
