[SunHELP] CPU usage for Process

[sunhelp at sunhelp.org]

Nitin,

Run mpstat 2 and note the amount of CPU time is being used on each processor.
It's likely that you have a single, single threaded process that is spinning
on a single CPU which shows up as 50% of the total CPU cycles available since
you have two CPUS.

Throw top away, it's garbage. You will get much better information from
vmstat, iostat, mpstat, prstat, lsof and netstat.
