[Mimedefang] timeout before data read?

Quite suddenly, and consistently, today at around noon, I started seeing
the following messages in my maillog, and the load average on the system
went through the roof (load average shot up beyond 22!) shortly afterwards.

Now, if I bring down both mimedefang and sendmail and bring it back up
again, I can get some mail to come through, but very little before it
starts spitting out these errors again.
And, it seems, that mimedefang keeps being forced to spawn a new
process, leaving the old one around to spin its wheels, and the new
process will generate the same error, and then spawn a new process
because of the failure, and so on and so on, becoming a very fast and
sick cycle. :(
I'm pretty much at a loss as to what could be the cause since neither
mimedefang nor sendmail have been rebuilt in quite a while (I am running
the latest mimedefang and the latest sendmail, of course). And no
changes have been put in to place in the mimedefang-filter either. :(
Right now, I am limping by only by watching the maillog, seeing a
failure of a slave, and restarting mimedefang as a whole... Of course,
I can't keep that up forever..
