Do you mean "stuck" as in they aren't moving and the CPU and disk usage
is zero?

It's possible that they've been deferred for some reason (server overload?)
and they won't get processed again for a certain period.

The only time I've seen this happen was with a server running Amavis that
started core dumping on a particular message.  I can't see any way that
the two would be related, except that a bug in qmail-scanner could cause
it to defer a message forever as well.
