What about the RedHat updates for 8.0? Are they in place?

System load doesn't sound like it is you problem. A load average of 1.5
is pretty much nothing. Now if it was running 15-20 that might be cause
for concern.

That should be plenty of memory for a mail server/scanner unless there

MailScanner bangs on the disk quite a bit as compared to just
sendmail/procmail. My suspicion is that the fault is associated with the
disk subsystem activity.

Are the system and RAID controller BIOS versions current?
