Are you able to identify when the problem occurs? This might let you associate the problem with an internal cronjob or network activity. What does ifconfig report? Does the interface look normal or is it reporting something strange? Is the switch reporting any events associated with your port? What do you see if you tcpdump the interface whilst its not working? Are you seeing normal subnet broadcast traffic? Unicast traffic directed to your box? Outgoing traffic from your box? Does physically unplugging and re-connecting the network cable correct the problem? Are you able to (temporarily) use a different swichport or NIC? Finally, more detail on your configuration might trigger someone's memory: What version of 6.x? What NIC/MII? How much memory? What network features (vlan, firewall, dummynet, netgraph, carp, ...) are you using? -- Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour.
