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

Re: zookeeper errors
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. - Mark On May 5, 2013, at 1:50 PM, Michael Della Bitta wrote: > 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?

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?
