>1. On 80 nodes cluster, did you reboot only one node or multiple ones? Tried both, result is same, but the logs/stacks are from stopping and starting glusterd only on one server while others are running. >2. Are you sure that pstack output was always constantly pointing on strcmp being stuck? It stays 70-80 minutes in %100 cpu consuming state, the stacks I send is from first 5-10 minutes. I will capture stack traces with 10 minutes waits and send them to you tomorrow. Also with 40 servers It stays that way for 5 minutes and then returns to normal. >3. Are you absolutely sure even after few hours glusterd is stuck at the same point? It goes to normal state after 70-80 minutes and I can run cluster commands after that. I will check this again to be sure..
