Strange load issue with 2.4.17

[Sebastian Hagedorn]

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 ...

Cheers
Sebastian
