Strange error in application log

We had a box go down today with the following error occurring a bunch
of times in the application error log:

"Error","cfthread-22","10/05/09","11:34:53","COLDBOX.CACHE.EXPIREBYKEYSNIPPET_25FB8E18916C6E3DE7D920AFD4C0F4A1:
Element OBJECTKEY is undefined in ATTRIBUTES. "

This seems to correspond to an error we are receiving from the
application: "A timeout occurred while attempting to lock
beanfactory.createmodel.util.resource.eventMetaService."

Has anyone seen something like this before?

We are running CB 2.6.3.

Anything unusual in the creation of the eventMetaService object? Any db interation, anything that might make it lock up. Also, I believe this is a bug also on the MT manager for expirations. I have logged a bug for it.

Fixed on SVN for 3.0
