This is usually the result of the nic hardware, after being given a packet to transmit(layer 1, if you will) being unable to issue an ack back up the stack to indicate that the packet was indeed transmitted before the specified timeout period - usually resulting in what appears to be a loss of network connection. Check the nic status (ifconfig dc0), netstat -Idc0 -d Check the physical network connection At the last you can always bounce the nic:- ifconfig dc0 down ifconfig dc0 up Test to see if the nic comes back okay Hope this helps., If not come back to the list with some info on which nic it is. I say this as there are some nic's that use the dc driver that are known to have flaky performance (eg D-Link, Kingston & LinkSys) under high load.
