Shalom,

The posted screen is not in itself a problem. It shows you may be under memory pressure.

I'd like to see the memory allocation in vmstat or swapinfo -tam

Some more performance data tools:

Memory leak detector in case an application is doing this to you:

All your applications have requested the amount of memory they need in order to run. This is normal and in HP-UX, the virtual memory system continues to allow more programs to run and use more memory than you have installed by moving idle program data out to the swap area. In Glance, this is measured with page-outs. So everything is running normally.

However, if the system is beginning to run more slowly, then you have reached the point where programs are paging in and out. You can either accept the slow speed or you can add a lot more memory, perhaps 100% more RAM should be added. Otherwise, you'll have to prevent some of the programs from running in order to prevent paging.

Do you really need 22GB of filesystem cache ?

If you are running a very very very busy NFS server maybe.

If you are running a database server then I suggest lowering filecache_max to something like 2% or 3% and give the memory to the database.
