swap full

[CSK Auto]

Hi everyone,

I am having problems determing what is causing the system to get 100% swap utilization over the last couple of months.

We are running HP_UX 11.0 with Informix DB.

I have been monitoring swapinfo and it is now at 100%

I don't have any po or pi.

I have been watching top and glance to futher evaluate the processes running.

I thnk we might have a possible leak

what other info do I need to determine this.

We have glanceand measureware on the system.

However, we do not have perfview to evaluate the output.

We do not have psuedo swap enabled.

Any suggestins would be greatly appreciated.


Thanks
Gwenn
