Swap memory use shouldn't trigger a reboot. You should monitor the process memory usage to figure out which one is causing the issue:

Code:
prstat -Z -s size

Update

Hi

Yes, you are right, but in my case none of the process related commands were responding in this case, until I reboot.

Only command like ls/date use to work.

But command like ps/top/iostat/prstat is not responding at all.

Thanks
Rajan
