Description of problem:
While running cerberus 9-20 on a pe7150 w/ beta3 installed, 24GB ram, 2GB
swap, perc3qc raid 0 container, bios x15.
Cerberus stops timer within 15 minutes, change of virtual console takes 30
seconds, top takes over 30 minutes to update. All swap space in use. All
but 8MB ram in use. Alt-sysreq is available. No disk IO occuring.
Steps to Reproduce:
1.Install fairfax beta3 on pe7150
2.Run cerberus 9-20 and note performance, responsiveness, and timer stopping
Actual Results: System all but hangs
Expected Results: Top should update frequently, virtual console available
immediately, disk IO should be evident, cerberus timer should continue.
Behaviour did not occur on a pe7150 w/ beta 3 installed, bios X15, 2GB ram, 2GB
Does this behavior happen with the 2.4.7 kernel, or with more swap added?
Yes and Yes. Kernel 2.4.7-0.12.0smp, with 24GB ram, 12GB swap. Heartbeat
stopped after 3 hours. Machine was still up but same unresponsiveness. Still
had sysreq access. Could not ctrl-c cerberus to kill it.
This defect is considered MUST-FIX for Fairfax.
Newburn ran for over 3 days with kernel 2.4.9-0.18smp and 32GB ram and 2GB swap.
Machine retained responsiveness and newburn could be stopped and started again
