This is kind of interesting in a morbid sort of way...
I've been running our test script for the last hour or so. It takes
about 4 hours to run on a modern iCore. I don't know how long it takes
on the Sparc.
Every 30 seconds or 1 minute or so the terminal ding's and this message shows:
Message from syslogd at gcc202 at Mar 9 05:31:14 ...
kernel:[827541.133057] watchdog: BUG: soft lockup - CPU#3 stuck
for 22s! [sshd:244056]
It looks like the issue has been reported on CentOS, Fedora, Ubuntu,
Suse, VMware. It also looks like there are a lot of culprits, from
over-commitment of resources to bad power supplies.
