Maybe your power supply is going bad and delivering marginal voltages?
Do you have it in a redundant config, or could you try adding a second PSU?

 A week ago, I ran every 32 bit Dell diagnostic I could on it ... for 4
 hours straight and not 1 error found. I also ran memetst86 for 3 hours
 and no errors found.

That's interesting but not really conclusive.  If it's taking 2-5 days for
FreeBSD to die, you're probably going to have to run memtest or prime95 at least
overnight (12+ hours, and it would be better to run them for longer) to really
catch anything.

I don't have an answer for you, but I had a very similar problem. It's 
why I'm running FreeBSD now. I had RedHat 9 installed on a Dell 2650 
running Apache 2, Postfix, Postgresql, Bind ... My system has a DRAC, 
raid, and a single processor. Actually I have 2 identical servers. One 
server is only for backup and lightly used and it never had a problem.


The symptoms on my primary server were exactly the same. Sometimes it 
would seize up twice in one week. Sometimes it would run for weeks. 
The weird thing was that it would respond to pings. However no system 
services responded and the console was totally unresponsive.


In frustration after not being able to figure out what was causing the 
problem, I decided to try FreeBSD 6 Stable. End of problem. I never 
figured out if it was the operating system, or an application or what.


If you're desperate, you might want to try the opposite: load Linux. 
If you're looking for something that feels familiar to a FreeBSD'er, 
try Gentoo.

RE: System Still Freezing

[fbsd_user]

System freezes are all most always (94% of the time) hardware
problems.
Power supply overheating, power supply voltage output falling to
low,
dust on motherboard causing overheating, or first signs of hard
drive failure.
Running mfg diagnostic will not identify these types of problems
until
they become close to total failure.

If you want to eliminate 6.0 as cause install 4.11.
That's before all the current major changes were applied.

But my money is on hardware starting to fail.

If I was you, I would make an backup to different hard drive of any
data I did not want to lose.

The warning signs are staring you straight in the face.

I had this happen to me and was so frustrated over it. Once I
replaced the
hard drive FreeBSD was installed on the freeze ups stopped. I still
am using
that HD in the same box for backup storage with out any problems
since. Go figure.

Hi all,

Another chapter in the life (and death), of my Dell PE 1850.

As you may be aware, I have a PE 1850 that has started to
intermitantly
freeze (this all started Feb 23rd). SOmetimes, it will run for 2
days, then
freeze, sometimes it can run as long as 5 days.

All logs and everything turned up to near debug, show nothing. The
system
just stops dead, and again, a physical suyvey of the server reveals
nothing.
All lights still working and blinking, no excessive heat not beeps
etc etc.

A week ago, I ran every 32 bit Dell diagnostic I could on it ... for
4 hours
straight and not 1 error found. I also ran memetst86 for 3 hours and
no
errors found.

Here are some particulars:

FreeBSD 6.0 RELEASE
Dell PowerEdge 1850
-Intel 3.0 GHz Duel Core.
-512 MB DDR RAn
-74 GB SCSI Seagate Cheetah 10k.
- 2 Onboard Intel Pro1000 (1 GB) NICS (Both connected to my switch,
1 LAN
and 1 WAN.).
- 1 Built in (Dedicated Riser) DRAC 4/I card.
- NO RAID, No Extra VIdeo or sound. No keyboard plugged in, no
monitor.

SHould I consider diableing APIC and Hyperthreading? Does anything
know if
these two would be causing all the issues I have in the kernel?

I have been reading alot about interupt storms lately. How can I
tell if
this is whats happeneing here?

Thanks again all,

-GRant
