Looks like dom0 is just about out of memory. It currently has 1 gb of
RAM. Looks like I changed menu.lst on Dec 12 to give it 2 gb of RAM, but
I haven't had a chance to restart it. It's been up for 29 days. It's a
dual quad core machine with 32gb of ram. It will probably run 12-18
domU's when all is said and done ranging anywhere from 512M to 4gb of
ram. Mixed Windows and Linux. Do you think 2gb of ram is enough for dom0
or should I go more, like 3 or 4gb?

"top" gives me:
top - 14:18:13 up 29 days, 17:41,  3 users,  load average: 0.47, 0.77, 0.71
Tasks: 302 total,   3 running, 299 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.4%us,  0.1%sy,  0.0%ni, 98.4%id,  0.7%wa,  0.0%hi,  0.0%si,  0.4%st
Mem:   1047040k total,  1036656k used,    10384k free,     7816k buffers
Swap:  2104472k total,  2104156k used,      316k free,    53876k cached

Thanks for everything,
James
