Non-Global zone take high CPU utilization.

UNIX Solaris
1

In Production system there is 12 Non-Global Zones. So in that 12 Non-Global zones one of the Non-Global zone taking 60-70% CPU usage and load average become very high.
Running processors are 52 only.

Please advise me is there any way to reduce the CPU sharing Utilization. (Most Urgent)

please use code tags to make your output better readable. also put the used command to get the output in you question too.

Hi Duke,

I am using the prstat -Z command to see the high CPU Utilization zone name. please let me know any idea regarding this. it would be great helpful to me.

something inside the zone needs cpu time... look inside the zone...

Hi Duke,

We are given on 30% CPU utilization limit for this particular Non-Global zone, but this zone will took more than Actual limit. That time load average reaches 340 (52 processors only running in the box). We rebooted the server also. Any alternate way.

does this happen on and off or continues?

7

is the server patched with latest patch cluster? which solaris release is installed?

8

Yes, but what is the kernel patch level for your system?
