I'm running Red Hat 4.1 full install
Intel DX4-100 CPU
100MB swap partition
Adaptec AHA-2842VL Vesa Local Bus SCSI
No IDE controller
Quantum 3.2 Gig SCSI hard drive (nice drive, by the way, real quiet)
JAZ 1 Gig cartridge drive
Fujitsu 128MB Magneto Optical cartridge drive
Phillips 8X CD-ROM drive
3COM ethernet LAN connection to NT box via Samba, X, telnet, etc.
I originally wanted to configure to a Cyrix P166/PCI with an Adaptec
Ultra-wide SCSI card but just could not get RedHat install to go
So, I stuck with my good ole 486DX4-100 - been running Linux for two
years, originally on Slackware (which gave me NO critical problems).
I decided to move to RedHat when the need for ELF binaries arose,
deciding I did not wish to hassle an in-place move to ELF and having
read that RedHat RPM was cool).
The system runs fine for most purposes. But. It hoses up at
various times which seem to be related to heavy use of memory
by either large Lisp processes or when I am copying very large files
to my JAZ drive (which I wish to use for daily backups).
I hate to be vague, but the problem or problems manifest themselves
in different ways.
Here are a couple of exemplars which appeared on one of my pseudo
terminals about the time the system hosed up or started to hose up...
I have LITTLE idea of what any of this means. I'm just copying
it to here in the hopes that a guru will see this and have some
wisdom to impart...

Any clues as to how I should proceed to diagnose, things to try,
etc., would be much appreciated.
