swap space is icreasing automatically in hp-ux

I have blade integrity server, OS is hp-ux . Here RAM size is 256.GB . This is datavbase server.

Here swap space is automatically increased day by day and when reached to 90%, server is hanged. Though RAm is using 60% that time.

have any solution to stop the swap increase automatically.....??

Re: swap space is increasing in HP-UX

You need to figure out which process is using the memory.

What does "swapinfo -tam" show before it goes bad?  Do you have top(1) output?

Re: swap space is increasing in HP-UX

That was "-tam".  You have plenty of free space now.

Your top output must list the processes, not just the CPUs.

Re: swap space is increasing in HP-UX

But my swapspace is still 60% used.  What is the reason for this.

You'll need to get the output of ps(1) and add up the amount of swap each process is using.

Swap usage increases because the application requests it.  It may have a leak.
