Apache2 + mod_proxy = server dying periodically

  • 772

I'm running apache2 with mod_proxy to forward certain requests to an nginx server running on the same machine. Occasioanaly the Apache server will stop responding all together until a restart. Checking the httpd.log shows the following lines happening every second or 2:

The timeout specified has expired: proxy: error reading status line from remote server localhost proxy: Error reading from remote server returned by /

I've searched google for an answer but found nothing definitive other than people mentioning mod_proxy as the cause.

Does anyone have a clue where to look next or even how to solve it?

Thanks, J

    Do you have KeepAlive enabled in your ProxyPass directive? I've seen this before, and in nearly every case, KeepAlive was the culprit.
