strange Kernel Process Threads taking over my AIX box....
- by Paul
When I check the Running Stats of my box I get the following:
CPU User% Kern% Wait% Idle% Physc
0 37.5 57.4 0.0 5.1 0.01
2 0.0 18.3 0.0 81.7 0.00
3 0.0 22.5 0.0 77.5 0.00
4 0.0 17.0 0.0 83.0 0.00
5 0.0 20.5 0.0 79.5 0.00
6 0.0 33.7 0.0 66.3 0.00
7 0.0 4.4 0.0 95.6 0.00
8 0.0 19.3 0.0 80.7 0.00
9 0.0 22.3 0.0 77.7 0.00
10 0.0 19.2 0.0 80.8 0.00
1 0.0 1.3 0.0 98.7 0.00
11 0.0 21.8 0.0 78.2 0.00
21 0.0 62.9 0.0 37.1 0.00
12 0.0 21.1 0.0 78.9 0.00
13 0.0 22.7 0.0 77.3 0.00
14 0.0 18.1 0.0 81.9 0.00
15 0.0 21.2 0.0 78.8 0.00
16 0.0 19.1 0.0 80.9 0.00
The Kern% seems high to me and I cannot find a reason for this much Kernel activity....
Doing a deep dive into what User processes are doing I find nothing with significant CPU utilization
even though TOPAS and SAR both show the same thing....
One CPU with 30-60 % user and every processor with 5-30% Kernel % utilization...
What is my box doing???
here is a second sample of CPU % from TOPAS
CPU User% Kern% Wait% Idle% Physc
0 67.8 31.4 0.1 0.7 0.14
2 0.0 18.2 0.0 81.8 0.00
3 0.0 20.3 0.0 79.7 0.00
4 0.0 17.3 0.0 82.7 0.00
5 0.0 20.7 0.0 79.3 0.00
6 0.0 39.2 0.0 60.8 0.00
7 0.0 5.0 0.0 95.0 0.00
8 0.0 17.9 0.0 82.1 0.00
9 0.0 22.0 0.0 78.0 0.00
10 0.0 18.0 0.0 82.0 0.00
1 0.0 0.7 0.0 99.3 0.02
11 0.0 21.7 0.0 78.3 0.00
21 0.0 21.7 0.0 78.3 0.00
12 0.0 17.0 0.0 83.0 0.00
13 0.0 21.1 0.0 78.9 0.00
14 0.0 17.8 0.0 82.2 0.00
15 0.0 21.8 0.0 78.2 0.00
16 0.0 17.6 0.0 82.4 0.00
Any ideas to help identify what is running in the Kernel Space would be great....
