-------------------------------------------------------------------
Hoss: Thank you very much for promptly following up. You are correct that you
can still query even after the exception happens, however, its a slowly
degrades to being a vegetable. You will see in the logs that as time progresses
the empty queries keep growing and finally we restart the glassfish, I must
admit that I may be a bit more paranoid/zealous than usual about relating the
exception with the empty queries, so take it with a grain of salt. :-)
Unfortunately since this is happening on production servers we had to restart
immediately and hence we couldn't get the thread dumps. However I have attached
the log file that show logs from sane to bust to restart of glassfish server.
Look for the word 'JBI' to mark start or stop of glassfish. I have also
attached the solrconfig.xml. Obviously I had to modify some paths and names in
solrconfig and log to obfuscate important details as per my company's security
policy.

> If you specify group=true but don't specify group.query or group.field SOLR
> throws a SEVERE exception following which we see the empty queries and
> finally no responses via solrj and admin console gives numFound always equal

> searcher goes for a spin once it encounters the exception. Such situation
