Sorry, I missed the original post on this.
We run a variety of Dell stuff where I work. Lots of 1850 and 2850 units,
and some 1950 and 2950s, in addition to a few 850s and the like.
We're not having any problems. We routinely see uptimes that span from
one maintenance window to the next without any unplanned reboots.
One thing we've had fun with is that Dell has issued a LOT of firmware
upgrades over the last year, and those are a pain to get applied to remote
systems. However, I don't recall any stability problems prior to the
I know this isn't answering your question, but I thought I'd point out
that your experience is not typical. Somewhere, you are having a problem
that _can_ be solved.
The various units you describe come in various configurations, I wonder if
you're picking a specific hardware combination that FreeBSD has trouble
Otherwise, you're on the right path with the crash dumps. Once you have
more details, post them to this or the -hackers list to see if you can
get the problem narrowed down. However, if these systems are spontaneously
rebooting without a panic, crash dumps might not help.
You don't have IPMI enabled on a public interface, do you?
