I had a very similar experience with a Dell PowerEdge 2800
recently, not even 3 weeks have elapsed!
The problem, as we realized from some Dell engineer, was with
the firmware on the mobo of this model.
I was running FreeBSD 4.11-STABLE on the box.
I bought HP ML350, migrated the whole setup to it and no problems
even as I speak now!
I am still waiting for a replacement motherboard from Dell (local
vendor) for the 2800.

There is a Dell 2850 that I setup as a server for a client, using
FreeBSD 5.2.1. It's been running rock solid, and the only update
I ever did was to update it to 5.2.1-patch14, which it will never
go beyond, as I see no need.

So, the moral of the story? Put the Dell aside, get a good HP and
sit easy.

| PERL_VER=5.8.7
| Its not all that stressed of a box:
| load averages: 0.14, 0.07, 0.06
| Mem: 235M Active, 367M Inact, 160M Wired, 33M Cache,
| 99M Buf, 81M Free
| Swap: 1024M Total, 1024M Free
| I've tweaked all the kernel values mentioned in the
| tuneable section of the manual, but the reboots
| continue.  The box runs radiator (a perl based radius
| server), apache+mod_ssl-1.3.x with php5, postfix-2.2,
| amavisd-new-2.3, courier-imap-4.0, pure-ftp, nrpe
| (nagios), net-snmp, ssh, and bind 9.3.1 all from ports
| (except radiator).  
| I run the same mail server setup on another server
| with no problem, although it processes far less mail. 
| I use radiator on another server with no problem. 
| This is a unique combination of packages I'm running,
| but no unique programs or configurations to this
