i have a problem with mbuf... when all my free memory is gone ( i have 2gb

I recently received an informal problem report that there is a problem with
the "denied" statistics gathering, so I think it's likely that's what is
going on here. I'll follow up with the submitter and see if we can't figure
out something more definite.
I have received some further information on the problem from the reporter.
Could you give this patch a try and see what effect it has?

Technically, there has been an allocation failure in this case in identifying
a bucket to return the item to, but since the overall case is a free,
generating a failure statistics update seems undesirable.
