kswapd - very high cpu usage

[Andrew Elliott]

Having some problems recently with a production server....where cpu usage
for kswapd is 100% and renders the system nearly unusuable.

 

System is RHEL v.3

kernel 2.4.21-20.ELsmp

 

swap usage is non existent....I think it may be related to heavy IO load on
the scsi array.

 

I've had this problem a few times before and the only thing that would fix
it is a reboot.

 

Any ideas?

 

Thanks.
