Subject: [PATCH] proxy_pass: clear backtrace on ECONNREFUSED
Date: Fri, 24 Apr 2015 11:11:49 +0000	[thread overview]
Message-ID: <1429873909-26696-1-git-send-email-e@80x24.org> (raw)

Bad connections or dead upstreams cannot be solved looking at a
backtrace, so avoid polluting logs with them and making other
problems less visible.
