Re: CPU utilization 100%
Please use Post Options > Edit Reply to insert the appropriate newlines so it is readable.
Also, it would help if the top output had the top processes.

Re: CPU utilization 100%
>I have given the vmstat & top output.
top and vmstat say your system is now idle.
Perhaps the peak was only temporary?

Re: CPU utilization 100%
There is nothing to worry about. 100% CPU usage will not cause your machine to melt down.
HP-UX, like all Unix flavors, is a timesharing system. A single process can easily consume 100% of one CPU. For a 4 CPU system, 4 of those processes running at the same time will consume all 4 CPUs. But you can still login, run vi, compile programs, look at web pages, etc. HP-UX will reduce the priority of 100% usage programs to allow everything else some CPU time. You don't "fix" the program or the OS...if you are not expecting the program to use 100% CPU time, then ask the creator of the program if this is normal or what the program is supposed to do.
