> I have seen several cases where there is a zero-length segments_n file. We 
> haven't identified the root cause of these issues (possibly a poorly timed 
> crash during replication?) but if there is another node available then Solr 
> should be able to recover from this situation. Currently, we log and give up 
> on loading that core, leaving the user to manually intervene.
