hi
We have migrated SCO 5.0.6 into ESX4, but the VM eats 100% of the virtual CPU.
Here is top print from the SCO VM:
last pid: 16773; load averages: 1.68, 1.25, 0.98 02:08:41
79 processes: 75 sleeping, 2 running, 1 zombie, 1 onproc
CPU states: 0.0% idle, 17.0% user, 83.0% system, 0.0% wait, 0.0% sxbrk
Memory: 512M phys, 447M max, 416M free, 441M locked, K unlocked, 2000M swap

Howto tune SCO 5.0.6 for VMware?
not sure about the SCO specifics running on VMWare but what is taking 83% system time? I cannot tell from the top output but you have two lpd processes in the run state. Is your printing daemons running properly? Can you post ps -ef?

Which process is hitting so much CPU usage?
Here is ps -ef output:

BTW on the old physical system is the same problem > 85.4% system.

Try running this:
#!/bin/sh
ps -A -o "pid=" -o "pcpu=" |awk '$2 > 5 {print $1 " " $2}' | sort -r +1
It will list all processes using more than 5 percent cpu.

There's one process that seems out of bounds (4th column is %CPU used):
root 390 1 95 02:48:50 ? 00:29:07 /usr/lbin/lpd -G
Check the printing configuration and log files for any oddities.

Thx, but howto check lpd log files or find lpd problem on SCO 5.0.6?

... and something under that process has died.
The manual implies that errors are in syslog but there is no mention of a "-G" switch to lpd.

And here is /etc/init.d/lpd startup script:

It's quite interesting, if I stop or start lpd, I don't get any error messages:
# /etc/init.d/lpd stop
Advanced Line Printer System stopped
# /etc/init.d/lpd start
Advanced Line Printer System started
Even the same problem happens, if I start using /usr/lbin/lpd
