My fileserver has sporadical hangups running 6.3:
FreeBSD 6.3-STABLE #0: Thu Jun 19 00:21:00 CEST 2008

The exact release doesn't matter since it happened before. It always
happens afer some time of having some load on the system (I'm building
ports with tinderbox and during the build process it just hangs up).
The system does nothing write out on the console, neither the CRT, nor
the serial console.
The system itself is:
CPU: Intel Pentium III (845.64-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x683 Stepping = 3
Features=0x387fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,PN,MMX,FXSR,SSE>
real memory = 805240832 (767 MB)
avail memory = 778481664 (742 MB)
ACPI APIC Table: <Intel N440BX >
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 1
cpu1 (AP): APIC ID: 0
ioapic0 <Version 1.1> irqs 0-23 on motherboard
while the diskspace is provided by an 3ware RAID:
twa0: <3ware 9000 series Storage Controller> port 0x2400-0x24ff mem 0xf4101000-0xf41010ff,0xf4800000-0xf4ffffff irq 18 at device 11.0 on pci0

da0: 715224MB (1464778752 512 byte sectors: 255H 63S/T 91178C)
I had - in the past - sometimes messages left which where indicating,
that the system was not able to allocate swap space fast enough if I
recall it correctly (_not_ out of swap space!) but the RAID is kinda
fast imho.
Any idea what I could do to shed some more light on this behaviour?
Why it is happening and what really is causing it?
Would enabling the kernel debugger really help here? I mean the system
is really hanging up - except ping response it is not responding to
anything except the reset switch ;)
Greetings, Oliver
install mbmon from ports. I had also similiar problems with old
motherboards with swelled capacitors.
Be careful with mbmon and healthd -- just because they compile and run
does not mean they're working properly (the values shown may be
completely unreliable/incorrect).
It's best to check such things in the system BIOS, unless you have
absolute certainty that your motherboard is supported by mbmon/healthd.
