Hello,

Our local test environment mini cluster goes nuts right after start up. It is a two node/shard/replica collection starts up normally if only one node start up.  But as soon as the second node attempts to join the cluster, both nodes go crazy, creating thousands of threads with identical stack traces.

If does not happen always, but most of the time i am unable to boot the cluster normally. Sometimes, apparently right now for the first time, the GUI is still accessible.

Is this a known issue?

Thanks,
Markus
