Subject Re: Solr zk client stopping sending data
Date Wed, 25 Jul 2012 14:56:10 GMT
Hard to determine from this info. With only WARN logging, you don't see a
lot of what is happening. Around what is the date of this build?

Close can actually be called quite often - it's used to cancel recoveries,
but new recovery threads can easily start up. What you should see if
Recovery truly gives up is: "Recovery failed - I give up."
