I have a system: quad-xeon-550
		 16Gigs of ram
		 2x18Gig internal disk (Configured / non-raid, /usr raid0+1)
		 4x54Gig external disk (Configured raid5)
		 Gigabit fibre network
		 kernel 2.4.18
		 Debian 2.2

  This box is supposed to be a corp mail server but it's being finicky.
In the past there were memory errors which ended up having to be fixed
with append="mem=6000".  At the suggestion of the list I backed down to
2.4.18 and compiled fresh.  This seemed to fix the memory errors.  Now
though when I try to rsync from the existing mailserver to the new
server memory usage climbs to 15Gig + and the load hits 15+.  When I let
it sit the load will drop but the memory free as reported y "free" stays
around 15Gig.  One time though it crashed with an "ACIC" error and a cpu
listing.  It was scrolling too fast to read and scroll-lock, etc were
unresponsive.
  At the suggestion of management (technical) I put the "mem=6000" back
in and rebooted.  It never came up.  Putting the console on I saw a
kernel panic.  Rebooted(hard with power button, no sysrq) with 
"linux init=/bin/bash" and I got another panic, slightly different.

Can anyone point to a potential cause?
