I was running 5.3 RELEASE. I just updated to 5.3-STABLE to see how things go.

FreeBSD shadow 5.3-STABLE FreeBSD 5.3-STABLE #0: Sun Jan 16 09:47:10 CST 
2005     root at shadow:/usr/src/sys/i386/compile/SHADOW  i386

This is a Pentium 4 3.06(HTT) and I have enabled SMP.

it runs very well, but anywhere from an hour to a week and the machine 
reboots. Last time this happened, I had disconnected the LAN from the 
machine in case something was causing this from the network. (nope).

I then thought it was related to SCSI, so I installed a new 5.3 on IDE. 
Still reboots. I have 2 identical machines and they both exhibit this. So I 
doubt its faulty hardware. These machines can run any other OS for weeks on 

Just freebsd 5.3 causes issues. 5.2.1 was rock solid for months and no 
reboots. (I dont do upgrades, but fresh installs..) so when I installed 5.3 
the trouble started.

last week I had a panic which caused the machine to halt and I posted it 
here. No dump file though and no reply. All I did was telnet into the 
machine and it panicked.

So...before I give up on 5.3, I wanted to see if there was anything I could 
do to help the developers track down this reboot_at_random troubles.

PS - these machines have less than 10 users and virtually no load. All they 
do is run DNS and SMTP.
