Hi All
I know that it was written a lot of about Kernel-idle process here, but I
need some suggestion what I should still check.
I thought about my problem and I think I have a bottleneck somewhere.
I have an AS 8200, 2CPU and 3GB RAM. I don't know why, but Oracle and other
applications are lazy today.
I checked the system and I found some abnormal things. The Kernel-idle has
2.8GB VSZ and sys time of CPU's is higher than normal (normal between user
and sys)
Our disks are conneted throught FC-switch and iostat shows average I/O about
9MB/s.
Thx for your suggestions.

I don't know what it's important of this list below. Maybe some time is
critical (first line with "*"), but I don't understand all lines.
