Awesome, i got a strange exception, searched the web for it and ended up here, 
again! This time it is Solr 5.1, i completely removed the data directory, 
restarted and indexed 18 million records. Then restarted Solr again, and got 
this slightly different stack trace:

There is no further real malfunction so this error could be ignored, but 
shouldnt occur anyway.

>             Project: Solr
>          Issue Type: Bug
>          Components: SolrCloud
>    Affects Versions: 5.1
>         Environment: 5.0.0.2012.11.28.10.42.06
> Debian Squeeze, Tomcat 6, Sun Java 6, 10 nodes, 10 shards, rep. factor 2.

>
> With SOLR-4032 fixed we see other issues when randomly taking down nodes 
> (nicely via tomcat restart) while indexing a few million web pages from 
> Hadoop. We do make sure that at least one node is up for a shard but due to 
> recovery issues it may not be live.
