Subject Re: Exception in thread "Lucene Merge Thread #3" MergePolicy$MergeException: java.io.IOException: Data error (cyclic redundancy check)

The traceback is truncated?

Still, this looks like your filesystem (and, specifically at least one
of the files it's holding for Lucene) is corrupted -- Lucene was
trying to read bytes from a file, in order to merge segments, and the
OS/IO system threw that exception.

You should run CheckIndex (which should detect & describe the
corruption), and then try to recover the index by re-running
CheckIndex with -fix.  But, more importantly, you need to figure out
why your filesystem has developed corruption because it will likely
happen again!
