Well, I recall FreeBSD 5.1 having problems with the RAID controller
that is being used by the PE 2650 (a DELL PERC 3/Di or something
wasn't it?). I don't know how it is with 4.9 though, never tried that.

We were using Nagios and MRTG on that Box, which is a monitoring tool.
And well, it had to get about 5 or 6 SNMP checks plus several port
checks from about 175 servers, so it had quite a load. Thus it
resulted into a complete system crash frequently.

Unfortunately I can't give you a real solution. The funny thing was,
I tried upgrading it to FreeBSD 5.1-CURRENT but that wasn't working
at all. So I reinstalled it again to RELEASE, recompiled the kernel
with the same configuration file as I did with the previous one, and
suddenly it was all fine. It has an uptime from 31 days now.

I know this message isn't going to help you too much, but I thought
it might be handy to know that you were not the only one having
problems with the Dell PowerEdge 2650.

Cheers,

Jorn
