Hi SAm, I actually had a similar problem myself, but was unable to prove it was the persistent connection itself causing this. I'm wondering if this means that INNODB thinks that a connection that is now 'sleeping' (ie. where a connection was created, used, but is now unused but still open) might be locking the whole table erroneously for some reason? Which version are you using? I could not figure out why Innodb would think the table was locked, other than if someone specifically said 'LOCK TABLE' in a query, which wasn't the case.
Any thoughts?
