Got a V Class server? Its your swapper.

[Steven E. Protter]

vhand is an i/o helper. If you are swapping to much or have other i/o issues this could cause your system to slow down.

Don't kill vhand.

Monitor performance and identify the issue. I am attaching a script that should help.

Well, you've got some HUGE problems here.

This server is severely constrained.

A) Change your swap priorities all to 1 in /etc/fstab:

dev 4096 3328 768 81% 0 - 1 /dev/vg00/lvol2
dev 4000 4000 0 100% 0 - 0 /dev/vg00/swap2

B) Buy more RAM immediately if you can, if you can't add more 2ndary swap. You're out.

total 11286 11050 236 98% - 0 -

C) You have a severe disk or tape bottleneck for you CPU averages 81% wait time.

C2) Any tape work going?

D) Disks c1t2d0 and c2t2d0 are 100% busy. What's on c1t2d0 and c2t2d0? O/S and swap?

D2) Move all of your 2ndary swap off of O/S disks and out of vg00. (* /dev/vg00/swap2 *)

In short, you're O/S is madly swapping out processes so buy some more RAM or turn off some processes.
