Hi all,
Is there any problem causes the cluster shutdown automatically?
All the ten nodes shutdown this morning.
We found this problem in 16th, and today it appears again.
The logs i can found around shutdown including:
The first node:
[There is no log befor this one today]

This log sames caused by the stopping request. After that, the node stopped.
The second:
Initially, some events about nodes left. (Since the first node is stopped)

followed with some similar logs, and finally stopped.
The third:

Similar logs with the previous one, and stopped.
Anyway i didn't find any useful information from the log.
