hello list,
For the past year we've been running several Dell PowerEdge 1750 servers
on FreeBSD 4.10, 4.11 and 5.3. All these machines have dual Xeons running
with HT enabled. This install has proven to be unstable in that the
machine will reboot between 3 days and 170 days without apparant reason.
No log is written. Other machines we have with a single CPU (HT enabled)
do not experience this problem.
As it is present in both 4.x and 5.x and googling the last year has not
revealed similar experience I'm consulting this list. As all of these
machines are productions machines that have a continuous load (not heavly
load, but a light average - some peaks) it's not easy to experiment with
HT setting etc. I dislike driving to the datacenter for locked systems
with fubarred kernels ;-)
The only error i've ever seen just before a reboot is "bge0: discard frame
w/o packet header" on the 5.3 machine.
Late comment while browsing the list for tips...
No good clues, I'm afraid, but we have a 2850, and it is far from stable,
crashing within hours when running SMP, often but not always under high
load. Single CPU works like a charm. This is very annoying, to say the
least. See my posts on amd64@ around June 15.
FreeBSD 5.4p1 (amd64). Dell 2850 with dual Xeon CPUS, EM64T.
