hi folks,
[i've posted the following message to -bugs@ a short while ago, but
then was directed here by a friend freebsder. while reposting, i
also corrected some minor facts i missed in the previous post]
i have a dell poweredge 2600 (4G ram, 2x2.8ghz xeon cpus, some disk,
full dmesg below), running a heavily loaded website (apache13, php, cgi,
pure-ftpd). this is a brand new 4.10-release install, brought to sync
with -stable, both exhibit the exact same problem), which every once
in a while crashes badly. 4.10-R did that every ~2.5 days, 4.10-S did
it for the first time after one day. (before that, system was running
4.9-stable on a poweredge 4600 with one xeon cpu, no ht, no smp,
no nothing like that, and was very stable).
i cannot entirely rule out bad hardware as this is a brand new system,
but we haven't had many problems with dell stuff before.
everything i think to be related is included below; if anything else
is needed just please tell so.
thanks in advance.
