Subject RE: Antwort: 6.6 Cannot talk to ZooKeeper - Updates are disabled.
Date Thu, 31 Aug 2017 08:00:05 GMT
Hello Stephan,

I know that restarting stuff can sometimes cure what's wrong, but we are nog going to, we
want to get rid of the problem, not restart microsoft windows whenever things run slow. Also,
there is no indexing going on right now.

We also see these sometimes, this explains at least why it cannot talk to Zookeeper, but why..
 o.a.s.c.RecoveryStrategy Socket timeout on send prep recovery cmd, retrying.. 

This has been going on with just one of our nodes for over two hours, other nodes are fine.
And why is this bad node green in cluster overview?

Thanks,
Markus
