A user here hit the exception the title says when optimizing. They're using
Solr 1.4
(Lucene 2.9) running on a server that mounts NFS for index.
I think I know the famous "Stale NFS File Handle IOException" problem, but I
think it causes
FileNoutFoundException. Is there any chance to hit the exception in the title
due
to NFS? If so what is the mechanism?
The full stack trace is:
