Hello @rzarzyns , If you look back at C2, you will see that the error is indeed from the cluster log, ceph.log. Also, given the very ephemeral nature of the problem, maybe a small code change to log something more at a regular logging level when this issue is triggered would be the best action here. Actions: Me: Explain issue and get the case closed Me: Write a KCS to help others ENG: Make code change so more data is logged when this issue occurs enabling better understanding in future releases Let me know what you think, thank you! Best regards, Manny
