[HPADM] Swap Utilization

Hello Admins,

We have a problem with a K-570. The problem is that the primary swap on that
box is pegged at 100% and we are not sure what has it pegged. We are running
this box as an SAP App server. We are getting dumps in SAP saying there was
an error in the free_page routine, or something to that effect. What I need
help with is finding out if there is a way from HP-UX to figure out exactly
what has my memory locked up. We are already planning a reboot and have
setup some monitoring scripts to kick off when the system comes back, to see
when the memory pegs. At least at that point we would have some kind of time
range as to when swap gets hammered. Before I would like to try to establish
what is eating up the swap, if possible. If anyone has any experience with
this and has any advice, I would greatly appreciate it as usual.

Thanks,
