I have used xml rpc library with transport http. My client and server are running on same host.

In normal load scenario(20% cpu usage, 80% memory usage, 18 GB memory free), some request of xml rpc client fails with connection reset by peer error. I have used xmlrpclib.ServerProxy() to call remote method on xml rpc server running on an empherial port.

This issue has happen many times.

log snippet,
