Comment (by Paul Netherwood <paul@…>):
I think I have successfully traced the problem. The time spent in place in
the scheduler was down to a sql statement that was creating a temporary
table. My sql database had grown significantly since I first setup the
database in 2006 and a retuning of mysql was necessary. After running
mysqltuner.pl and a few other tweaks I was able to bring the place time
down from 200+ seconds to 1-2 seconds. Since then there have been no
occurrences of the lockup.
Please close the ticket.
Thanks
