Uneven load sharing by CPU's on N-class server....

Hi,
For last 15 days or so, we are facing a very strange problem. We have two N-class servers. Both are running the same application and have same hardware configuration. On one of the server, only one CPU is taking maximum load. Following is the o/p of the "top".
System: IBBS1 Mon Feb 12 19:17:11 2001
Load averages: 5.75, 5.57, 4.92
1950 processes: 1940 sleeping, 10 running
Cpu states:
CPU LOAD USER NICE SYS IDLE BLOCK SWAIT INTR SSYS
0 16.91 41.6% 0.0% 58.4% 0.0% 0.0% 0.0% 0.0% 0.0%
1 2.39 9.7% 0.0% 38.1% 52.2% 0.0% 0.0% 0.0% 0.0%
2 1.83 17.7% 0.0% 32.7% 49.6% 0.0% 0.0% 0.0% 0.0%
3 1.85 16.8% 0.0% 27.4% 55.8% 0.0% 0.0% 0.0% 0.0%
--- ---- ----- ----- ----- ----- ----- ----- ----- -----
avg 5.75 21.4% 0.0% 39.3% 39.3% 0.0% 0.0% 0.0% 0.0%

Can somebody help me regarding the same.

Hi,

Glance or top allows you to identify the processes that are running on a specific CPU. In this case, check out the processes on CPU 0 and pin-point the one with the heaviest CPU usage.

This is especially easy with glance because glance allows you to sort by individual columns the entire process list.

Hope this helps. Regards.
