The problem is that, after one node of the cluster fails and restart, the remaining nodes fail to shut-down gracefully and their JVM has to be killed.
The default shut-down is 1 minute: it has been extended to 5 but the nodes still fail to shut-down.

Find attached:
- the complete log of one node failing to shut-down (17293.log)
- the thread dump of this node just before being killed (after a 5 minutes time-out) (perf20-consoleText.txt)
