Sounds like your index may be corrupted. Run checkindex. See similar discussion at:

Subject: SEVERE: null:java.io.IOException: Input/output error: NIOFSIndexInput 

I have a Solr 4.2 (with Lucene 4.1 index version) server setup on a CentOS
6.4 x86 and Java:
OpenJDK Runtime Environment (rhel-2.3.8.0.el6_4-i386)
OpenJDK Server VM (build 23.7-b01, mixed mode)

Currently it has a 4.6GB index with ~400k records. When I serach for certain
keywords, Solr fails with the following message:

Any idea why this happens? Can I repair indices?

Thanks.
Mohsen
