Hello, I have a problem with stock 2.2.13.I have a machine that serves web traffic at about 10Mbps (as mrtg says),and recently,with the bandwith increase from 5 to 10 Mbit I had interesting problems - after about 14 hours of serving trafic at about 10Mbit,the machine stopped responding to pings.When it was rebooted (it's 10K km from me,I couldn't see what has happened) ,it ran normal,and the logs showed that it accepted ctrl-alt-del and rebooted normally - i.e. it wasn't hung...I'm beginning to suspect (i'm probably,very probably wrong) that the NIC driver stops when it oferflows and wraps it's RX/TX counters.
Here's the output from dmesg :
