[learn_hp_ux]

I am new to hp ux system, need your expertise to advise me on below problem.

we have a machine rp3410 with hp ux b.11.11. The problem is from top command I got load average between 10 to 30, but the idle is between 80 to 90 %. Application can run but slow and if we open few application simultaneously it will automatically closed the application.

What is actually wrong with this machine ? Is it hardware problem or software ?Really appreaciate all your advice.

some initial checking should be performed.

1. Check kernel parameters.
2. check OS configuration files
3. Application requirements.
4. Resource(CPU, Memory,swap) utilization.
5. check buffer,no of opened files etc. utilization

This may imply that you are creating lots of short lived processes or you block a lot on I/O or swap.
What does "swapinfo -tam" show?

Well, you aren't swapping.
Do you have glance/gpm installed?
