Nothing there seems to bad. I personally don't like 3com cards, but that
shouldn't cause the problem you experienced. Make sure you don't have
the frame buffer running or any graphical interfaces on this machine as
it might cause the problem via the excessive interrupts to handle the
video. I also don't like software raid for a critical machine, and would
suggest at some point you try a single drive with no software raid. I
suggest it as a last item to check type of thing though.

Eventually you should probably upgrade to newer versions if nothing else
solves your problems.

Since you said in your original message that this occurred with inbound
PSTN calls that where navigating your IVR, I would look into anything
causing interrupts on your system or software that may be causing
blocking.
