Hi Patrick, Which nic is it? 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 <wait for a few seconds> 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.
