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...
