I have a vague hope that an infinite loop related to another MIME

I'm trying to get some things cleaned up so that I can make a release
today or perhaps tomorrow with that fix as well as the other recently
reported MIME problem.
We'd seen this on a few occasions running 2.3.45, with one or two
threads getting stuck. It wasn't giving us much trouble, with a quick
restart fixing the problem for a number of days. Until this weekend
when all hell broke loose, all email was locked solid when I came in on
Monday morning, and dccm wouldn't stay up for more than a few minutes
without turning back into a total CPU hog. Installing 2.3.51 appears to
have fixed the problem.
So: has anyone else seen this? I'm wondering if it might have been a
deliberate DoS attack. Do we know what qualities of a message caused
the problem? The other alternative is that it wasn't malicious at all
but was a mass mailing of (badly formed?) email.
Cheers,
Rob
