Hi:

It's because you have the kernel parameter swapmem_on = 1

You are using pseudo-swap. Look this thread:

Karthiknarayn,

If you ain't swapping that much, that is a good thing, becuase nowdays the systems are not supposed to swap.
Probably like Miguel said, somebody enabled pseudo-swap on the machine, or you added more memory, or a heavy load app is not running on that box anymore.

Regards,

Jaime.

Shalom,

SEP wisdom ( this just came to me today ).

Most swap problems are really memory problems.

Get the system some more memory or decrease the demand for memory.
