- Now what did I screw up? 
- Kinda embarassing to have it running so slow. Also I got the following
- message in the SYSLOG:
- 
- Jan  7 22:52:32 lucy unix: WARNING: Process [ksh] pid 12308 killed due to insufficient memory/swap.

I would also zoom in onto those ksh processes, which should not use anywhere
near two minutes of CP time (other than to allocate all that memory :-)

lisa is obviously using the system console and even that ksh seems overblown.
Where does sbernst log in from ? And what is using 92% of the machine in 
system time ? It cannot really be paging, since that is paced by the disk response speed, not the CP time available for it, so you would see some 15%
system time and 60% idle time.

We sometimes have situations like that, usually it is a terminal that has
disappeared from the network, and the application ignores that fact and keeps
reading and acting on end-of-files. Ksh, csh, sh, vi, emacs, all of them are
vulnerable to that. However, IRIX has usually be fairly undisturbed by these
louses, we see them more often on AIX. And it also seems impossible to create
them under controlled conditions, though users never have difficulties to 
encounter them :-(.
 
- P.S. The cute "R4000" medalion that comes with the upgrade kit is
-      very niffty...I put it on the lower right front cooling vents
-      like the directions said...kinda' reminds me of the grill medalions
-      on our old (1982) Mercedes TD300 diesel wagon :-)

"Tacky" is what I told our sales people here. But think of the 
possibilities: Rallye strips, decals, duotone paint schemes, ...
