Re: Query Stuck in "closing table" State
Just as an additional data point, the query does seem to eventually
complete (and the transaction it is in commits) after about 2 hours.
But 2 hours seems an excessively long time for "closing tables". It
is a simple INSERT ... SELECT ... ON DUPLICATE KEY UPDATE, with a few
triggers on the table being inserted into firing off. The SELECT on
it's own takes only seconds to complete. The UPDATEs fired off by the
triggers complete in milliseconds.

The one event that is running must be it, then. I specifically
