Are you using mod_proxy_ajp and load balancing between backend servers?
We used to see this error a lot but when we added timeout parameter to
BalancerMember directive if went away.
You may also want to try this or add the same parameter to ProxyPass
directive (timeout=300).

Subject: 502 proxy error
Team,
When I try to access an application using reverse proxy, most of
the time I will end up with below error. Anybody have an idea what will
be causing the issue? After few refresh on the page I will get actual
page but most of the times end up with below proxy error
Proxy Error
The proxy server received an invalid response from an upstream
server.
The proxy server could not handle the request GET /testingtool/.
Reason: Error reading from remote server
------------------------------------------------------------------------
--------
Apache/2.2.3 (Fedora) Server at testingserver.test.com Port 443
Thanks,
Isha
Aoache is the proxy, is it?
It could be the back-end server is not working reliably - what happens
if you access it drectly?
If it seems OK, how long does it take to respond? If it's a slow
application it may take longer than apache is prepared to wait (see
ProxyTimeout, KeepAlivetimeout)
Rgds,
Owen Boyle
