Thank you Gaurav, Here is more findings: Problem does not happen using only 20 servers each has 68 bricks. (peer probe only 20 servers) If we use 40 servers with single volume, glusterd cpu %100 state continues for 5 minutes and it goes to normal state. with 80 servers we have no working state yet...
