I received the exact same message last month, and again this month.
First was at five a.m., when nothing particularly was running, the other
was at 11:30 a.m., when the logs also showed some light activity. Like
you, I also checked the whiz-bang GUI, which showed nothing extraordinary,
and top, which showed all normal. This second time, I asked my VAR to
follow through with Cobalt. They got back a week later with a very
vague reply, which basically reiterated the message from the server.

One sensible thing they did suggest was that (if mail relay is open) the
overload may have occurred as a result of a spammer overloading the
mail. You might look at that.
