Well I think my problem is solved. Someone else pointed out that sometimes
a guest system's clock stops advancing and causes a problem with the
kernel's network stack:
http://www.linuxquestions.org/questions/linux-server-73/centos52-vmware-host-stops-responding-on-network-661399/
I have always noticed my guest systems' clocks always ran significantly
slower than the host's clock. I did some searching and found that one
workaround for this was to add the flags "nosmp noapic nolapic" to the boot
kernel's entry in grub:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1420
My guests have been up for almost a week now so far with no ill effects.

Nothing unusual appears IIRC when I run ifconfig. I am unable to ping

So far only a full restart would make the problem go away.
I just realized I haven't looked at my logs; I'll check that out later.
Please don't top post. It makes it hard to keep track of the thread.
Sounds like the NIC driver is bombing. What NIC is it and what does lsmod
show before and after the failure? Seems to me the problem is the NIC
module is hanging up and on a restart gets unloaded and loaded up again
fixing the hang.
