This is off a mailserver, these came up when i tried to cd to cur/tmp 
directories inside a maildir. There are process in ps all over the place 
and performance is terrible. The machine is running 2 fujitsu scsi 
drives (new but factory repaired and running in raid 1) on an older 
scsi/raid controller. This is the 2nd time this happend in the last 
week. Should i rather suspect a dying controller or the drives?

Thanks,
Petr
