Hello everyone: I found an error when backing up a volume with oslo_privsep,it seems that the client channel use a thread to receive socket message,but the thread may crash with inner exception unhandled while the main procedure continues,so I report a bug and upload a patchset to fix: https://review.openstack.org/#/c/369786/, what I did is just ignore the timeout exception when receiving message. This change seems a little arbitrary and unreasonable,so I start this thread to raise attention,please add your advices or solutions. I will abandon this change if any better solutions provided Thanks TommyLike.Hu -- It is not the mountain we conquer but ourselves. -------------- next part -------------- An HTML attachment was scrubbed...
