@nimda Other instance operators reported similar issues. If you see a lot of "request timeout" messages in your log, increasing queue size probably won't help.
@silverpill looks like only 107 entries, starting with this one

@nimda Yes, detroitriotcity being unresponsive is a possible cause but I agree that 107 timeouts is probably not enough. Do you have any messages with ERROR level in the log?
