It usually involves the watchdog kicking them back into order, but sometimes they'll stay offline for a while. Heat would explain it, though, because it only happens when I'm actually using the cards for a benchmark. I figured that it was either my cables, or a shoddy switch. The new dual-port e1000 that I have doesn't seem to have this problem, even though I'm running 4 times more traffic than the singles that I had. -- Dave Hansen haveblue@us.ibm.com
