We saw the file descriptors peak out and full GCs running causing DOS on our
SOLR servers this morning.

Subject: suspect SOLR query from D029 (SOLR master)
Looks like a suspect SOLR query was executed at approx. 8:54am this morning on
the SOLR master server (D029) that caused the java GC to go through the roof.
See below:
2014-05-30 08:54:17,092 ERROR - SolrDispatchFilter -
null:java.lang.OutOfMemoryError: GC overhead limit exceeded
