Hello all,
I've got a little problem with a new computer we have on our company. The 
problem is what I try run Cerberus to test the stability of this computer 
with a 2.4.13 kernel;  at the first test the computer went down in 15 
minutes; the second test went well, the computer responsivity was good and 
it was appears to be stable. At this moment I'm going to test again to see 
if the machine supports it (I hope that ...).
Well, now the problem and the question: what kernel do you think I must 
put on this computer? I need a rock solid system ... I'm testing 2.4.3 and 
2.4.9 too, but 2.4.13 appears to be the best performance kernel ...
Thanks in advance,
	Joan

2.4.12-ac6 should be able to survive Cerberus.

I have the same problem with a DELL 8450 4xPIII 4GB ram. I install
2.4.13-ac3,  he uses VM by Rik and I'm testing for two days and he is running
ok.

As you suggested, I ran the test again with Linux-2.4.12-ac6, 
Linux-2.4.13-ac4 and Linux-2.4.13, this time with ext2 filesystem (the 
previous cerberus run was run on ext3 partitions).

We've been unable to reproduce the system freeze with these kernels. Even
2.4.13 has remained stable, so we're again running ceberus on 2.4.13 and
ext3 partitions. If the machine stops again perhaps this is an ext3 related
problem or a bad interaction between the SCSI driver and ext3.

With respect to the differents VM in Linus and Alan trees, vmstat shows very
different numbers with respect to I/O block processes, bi and bo, and the
"jittering" of the VM. In Linus tree blocked processes and bi numbers
remains stable, while in Alan tree this values change a lot more.

Another point is that while Linus tree almost never touches swap, Alan tree
uses it right from the beginning.
