I've just been made aware of this issue also (non SOLR), also deployed with
Tomcat, but Tomcat is not part of the thread stack where the problem is seen.
It's with Lucene 2.3.2 and Tomcat 6. It seemed to occur for a week at the end
of October, but has not been seen since.

It doesn't have to be doing a search though as it also seems to happen in the
IndexWriter.AddIndexesNoOptimize stack too.
