Amazon ActiveMQ drops connection for long running listeners about stomp

[gmallard]

Unlikely that this is a gem bug I think. You are operating in a complex network environment. And as with all networking apps, any thing can go wrong at any time.

Any chance of you showing me your logs ?

Make sure your custom logger emits all the information it possibly can. Including original exception ans stack trace data if possible.

In the logger, try things like:

# Log miscellaneous errors
  def on_miscerr(parms, errstr)
    begin
      @log.debug "Miscellaneous Error #{info(parms)}"
      @log.debug "Miscellaneous Error String #{errstr}"
      @log.debug "Miscellaneous Error All Parms #{parms.inspect}"      
			if parms[:ssl_exception]
		               @log.debug "SSL Miscellaneous Error Parms: #{parms[:ssl_exception]}"
		               @log.debug "SSL Miscellaneous Error Message: #{parms[:ssl_exception].message}"
				btr = parms[:ssl_execption].backtrace.join("\n")
				@log.debug "Backtrace SME: #{btr}"
			end
    rescue
      @log.debug "Miscellaneous Error oops"
    end
  end

Do you have access to AMQ logs ? If so, do they show anything "interesting" ?

Looking at your connect hash: have you tried using well selected values for heartbeats ? That is a shot in the dark, but it might help.

I changed your code above just enough to get it running here. Started it.

Also started two producers. One sends to queue 1 every 30 seconds, the other to queue 2 every 20 seconds.

Connections to AMQ on localhost.

Right now, that has been running for about 20 hours with no failures.

I doubt tat I will be able to recreate this problem.

[gmallard]

I cannot recreate the problem you describe.

I have had your code running for as long as 4 days, with no problems.

If you need help from me I am going to need to see all of the detail in logs from the logger.

Incidentally, there is an enhancement to the example logger the gem provides. It is on the DEV branch only at present.
