Java Non-Global zone take high CPU utilization.
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)


Code:
ZONEID    NPROC  SWAP   RSS        MEMORY      TIME       CPU      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.
