Gordon,


I have see the Logs  of the Qpid container which had high memory usage,  application logs
seem to be normal however I see many  error logs.

These error logs constitute to 70% of the total logs generated by Qpid Container. Below  are
some of the error logs. Could these error logs indicate something?

I think trying to find what else changes when the memory starts growing
would be the best way to progress. I assume there is nothing in the logs?

Perhaps try getting qpid-stat queries periodically to try and see if the
differences over time show anything?
