Basically, when 'unexpected' happens, someone (e.g., operator) needs to know about it and look into it to see if it is something benign or fatal. If it is masked, the system may degrade overtime unnoticed into unusable.

In this case, the exception is just hard to debug, and not something we expected in our design. The thorough solution would be to debug further to see the root cause, and deal with it as I suggested in the code review. However, If it is time consuming to debug, we can put the patch in there with logging to record the circumstances the 'unexpected' exception occurs, so that we can put in new patches to deal it when it becomes expected. After all, this is an iterative process. When the software evolves, a lot of unexpected has become expected. -----Original Message----- From: Raymond Pekowski (Code Review) [mailto:rev...@openstack.org] Sent: Tuesday, June 25, 2013 9:52 AM Cc: Dirk Mueller; Andrea Rosa; Ben Nemec; Chris Behrens; Eric Windisch; Russell Bryant; Qing He Subject: Change in openstack/oslo-incubator[master]: Make AMQP based RPC consumer threads more robust Raymond Pekowski has posted comments on this change.

Patch Set 12: By definition, unexpected exceptions are unexpected, so there is nothing yet to do root cause analysis on.
