Hi,

I'm too still having this issue. It popped up again on the weekend. 
Saturday night I started getting SMS messages about issues with cpu user 
and cpu wait. As I was away from civilization, I was only able to 
disable system monitoring at half past eight yesterday. 134 messages, 
I'm quite certain they're fake.

Now I enabled monit system monitoring and the problem still there. I 
look at top and there's nothing, monit talks about 91.x% cpu user usage. 
 So I made monit to alert only on "3 times per 3 cycles", same problem. 
Looking at top, the machine is mostly idle. Only occasionally goes cpu 
user over 30 and that's when both CPU's are combined.

There's definately a bug. But it appeared only the night before on that 
box, it had a monit uptime of something like 60 or 80 days. I reloaded 
monit and still have this issue (uptime is reset).

Did Matt's /proc/stat output help resolve the issue?
