OHS Reverse Proxy 502 Bad Gateway Errors
Hello
I have OHS setup using mod_proxy to a backend application server using ssl. The proxy works most of the time but for some clients and periodically the server will just start failing and just hand out 502 bad gateway errors. The below errors are thrown in the event log when this starts happening. If I reset the server then it clears and starts working again. I am running v11.1.1.6.
[2012-03-26T16:32:49.1860-04:00] [OHS] [ERROR:32] [OHS-9999] [core.c] [host_id: <gateway] [host_addr: <hostip>] [pid: 1848] [tid: 2440] [user: SYSTEM] [VirtualHost: vr:0] proxy: pass request body failed to backendip:443 (dnsname) from clientIP ()

Below is the virtual host config for the virtual host.

Any help you can give would be appreciated on this.
Thanks
