Thanks for your reply. I agree that it doesn't really look like bug 3744.
System CPU *does* increase when the load starts to spike. It only goes to about 20 percent, but it's still a notable increase. Most of the system *appears* to be idle, but interactively you have to wait for each character you type to appear on the screen. My first assumption when dealing with a mail server is that all issues are I/O-related, but usually we would see an increase in Wait I/O when something was up ...

Apologies if I'm misreading, but that bug suggests many processes are created over a period of time. In contrast your grab shows the number of processes hasn't grown but the load has grown exponentially. I'd say it's not the same bug. The grab shows system CPU staying around the same, contrary to your description - which of them is correct? If load has increased while the CPU has dropped, I'd say you're still waiting on IO.
