Q: Server 5.1 proxy errors

Running Mac OS X 10.11.4, with Server 5.1. Serving a bunch of different websites. The upgrade from Server 4 to Server 5 was a bit painful, with the addition of the HTTP proxy layer, but everything is--or was--working. Actually, things still work, sometimes, but under any load at all, I'm seeing a lot of this:

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



Anybody have any ideas as to what changed in Server 5.1 from 5.0 that would cause web server performance issues?

    I am getting this too on a 10.10.5 server with server app 5.0.15.

     

    The only thing that changed recently was the update of Kerio Connect from 9.0.1 to 9.1.

     

    This combination works fine on several other servers.

     

    The logs do not seem to reveal anything happening before the proxy server stops working.

    The work around is simply to stop and restart web services but I am still looking for a permanent resolution.
