At random times I drop connectivity between the servers and their gateway. I am able to login via the secondary interface and "/etc/netstart" and everything starts behaving as normal. My switch shows the link is up, ifconfig shows the link is up, but I am unable to ping my gateway until running "/etc/netstart". Somedays it'll happen a few times an hour, some days once every 8-10 hours. It really is intermittent, and driving me crazy trying to track down the issue. I've tried different cables, switches, gateways, IPs, and locations. Memtest for 5 days showed no errors. However, the same problem exists on two separate installs at different times. I am able to connect to the one server from the second via their secondary interfaces, so the problem isn't related to both network interfaces. Both servers have the Supermicro X7SLM-L motherboard, same CPU, RAM and disks. Using the Realtek network driver (re). pciconf shows: vendor = 'Realtek Semiconductor' device = 'Gigabit Ethernet NIC(NDIS 6.0) (RTL8168/8111)' class = network subclass = ethernet I've experienced the problem for some time now on both 7.2-RELEASE and 7.2-STABLE (09/20/09) using amd64. Any help or suggestions would be useful in getting to the bottom of this. Thanks, -c
