Very Computer

My PC freezes every 3 or 4 days.
And when it freezes, I can not do anything except power-off.

Hardwares:
I'm using DELL PowerEdge 6350 with 2 Pentium II Xeon(400Mhz).
On this PC, 4 Adaptec ANA-6922A network interface cards installed.
(6 or 7 ports are connected to Macintoshes directly, and the 6350
is fast mac-file server.)
One external Ultra-Wide SCSI HDD and UPS are connected.

Softwares:
I've installed Red Hat Linux 5.2.
After normal "Server" install, I disabled sendmail and innd and
named and pcmcia, and added netatalk and dhcpd and smupsd.
And updated the kernel to 2.2.1, and updated required packages.
The kernel is compiled with SMP.

I've tried to change NICs and its driver-module, Intel PRO/100+
Management Adapter x7, and 3Com 3C905B x7.
It made no difference.

I've tried to chage the netatalk, from 1.4b2+asun2.1.0 to 2.1.3.
It also made no difference.

I've tried to chage the kernel, 2.2.1 and 2.2.5 and 2.2.9.
It also made no difference. (or getting worse ?)

One day, I watched the PC freezed, on which xosview displayed
cpus' load;   "CPU 0  100%" and "CPU 1  108%".
I can not get any other information from the PC.
It may occures when loads are very heavy.

Is there any way to run 2.2.x  SAFE  on PowerEdge 6350 ?

Thanks
