SolrCloud: CloudSolrServer Zookeeper error.
Hello everyone,
I have developed a NRT Java app that indexes documents using a
CloudSolrServer instance. During my tests I have a SolrCloud composed by
only one shard and two Solr server instances. During the several tests I
did found just in one case the following error:

Probably it might be related with some kind of out memory unavailable
issue, because I´m doing the tests in a very limitated machine, but maybe
the origin is different and someone could tell me more about it.
Thanks a lot in advance.
