Yep, this is exactly the problem. These processes do not use "much"
cpu, but they "blip" every 10ms or so. You need to check the queue from
the z/VM side to see if they are in Q3. If in Q3, then they are blipping
(think i need to trademark that word).
The reason these "blips" are so virtual unfriendly - think about poor
old z/vm storage management. We need to steal some pages for some real
work going on. Do we steal it from the server doing real transactions?
or from the one that is blipping? oops, we can't tell the difference.

I¹m looking at my system which has mod_mono in the apache config file and

The system's been up for:
4:56pm up 39 days 4:37, 1 user, load average: 0.00, 0.00, 0.00
What level of mono is installed? Is it registering when there's nobody
connected via http?
