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
