Error log: Failed to proxy response to client

[AlexanderPico]

Any guesses why we have this error message in our CyAppStore logs every few minutes?

[wsgi:error] [pid 28648:tid 140327797098240] (70007)The timeout specified has expired:
 [client 27.17.130.79:16711] mod_wsgi (pid=28648): Failed to proxy response to client.

My general guess is it is something related to our server being overloaded and not being able to respond to a request within stipulated timeout (configured in apache config file). I am trying to pin point to the exact requests causing this.
