Adaptec Quad Nic Problem

[Alexandre Biancalana]

 Hi All,

     I have a Firewall/Gateway running FreeBSD 4.8-STABLE connected to an internet link of 2.5Mbits/s througth an Quad-NIC Adaptec ANA6944A, that when having a high""traffic the switch port where the machine is connected points that's is down and the following messages appear in /var/log/messages:

 Sep  8 10:53:41 Krusty /kernel: sf0: watchdog timeout
 Sep  8 10:54:59 Krusty /kernel: sf0: watchdog timeout
 Sep  8 11:01:53 Krusty /kernel: sf0: TX ring full, resetting
 Sep  8 11:01:57 Krusty /kernel: sf0: watchdog timeout

 Sep  8 12:03:38 Krusty /kernel: sf0: TX ring full, resetting
 Sep  8 12:03:41 Krusty /kernel: sf0: TX ring full, resetting

 The transfers don't exceed 1/2 off total bandwitch available in this link, that's 2.5Mbit/s but the transfers don't exceed 700 Kbit/s.....

 After google, I have seen some case about that but without an solution.
 Someone can help me !?

   Best Regards,
