Whatever you are referring to is not here.  The mailing list eats most 
attachments -- they don't make it through.

If you edit server/etc/jetty.xml you'll find a commented out section 
that enables request logging.  Remove the comment marks, restart Solr, 
and you'll get a log in server/logs that will include the source address 
for all requests.  You won't be able to tell which core sent the 
request, but narrowing it down to which server sent the request will 
probably be enough to investigate further.  You will need to make sure 
that you have good time synchronization on the servers so that 
timestamps in logs will match up.
