The server had 4 x e1000g and it was showing high latency on all four at the same time at random intervals. After days trying to isolate the problem, we checked pretty much all and everything related to the network/CPU, the only solution was too reboot and see what would happen. The problem stopped and never happened again on any other machine. That being said we are not sure what caused it but perhaps a switch/interface problem, IRQ sharing storm, etc. Can you let your other computers ping'ing this one and see if it shows the same delay ? -- Giovanni
