Occasionally I'll see a bge0 timout + reset error logged, but many times I'll just see a "socket closed unexpectedly" type of message from postgres. So far, every 5 days or so, the machine freezes during heavy DB reporting over the net. I have a S2881 mobo, though, with 4GB. I had another identical machine which was reporting in the BIOS that the memory size changed during normal operations, which was very scary... Vivek Khera, Ph.D. +1-301-869-4449 x806
