zookeeper errors
Hi,
I'm running a Solr 4.2.1 cloud with an external three-node Zookeeper 2.4.5
setup.
I'm seeing a lot of these errors in the zookeeper logs:
2013-05-05 15:06:22,863 - WARN [NIOServerCxn.Factory:
0.0.0.0/0.0.0.0:2181:NIOServerCnxn@349] - caught end of stream exception
Also some of these:
NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@354] - Exception
causing close of session 0x3e22c637f5063f due to java.io.IOException:
Connection reset by peer
or
NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@354] - Exception
causing close of session 0x3e22c637f506a1 due to java.io.IOException:
Connection timed out
We've had problems with nodes dropping out of collections during indexing.
I'm assuming these are related? Is there some sort of socket tuning I need
to do on the Solr side to keep these connections going?
Thanks for any input anybody might be able to provide,
Michael Della Bitta

Mark,
I'm definitely using CMS, so I'll look into the zk client timeout.
Thanks!

It sounds like you probably need to raise the default 15 sec zk client timeout. We have it default to a fairly aggressive setting. For high load envs, you may have to bring it to 30 or 45 seconds.
Also, be sure you are not using a stop the world gc collector - CMS (the concurrent low pause collector) is best.
