Hi Reyk, Thank you so much for your help and interest.
The machine in question is working as a anti-spam bridge. It was passing traffic normally until the problem occur. After that the conectivity was lost between the internal LAN and the external world. It went operational last friday at 21:12 (GMT-3). The problem occured this monday at 7:09am (GMT-3), as shown in the log entries below. So, it took about 2 days and half. May 26 21:12:55 wall savecore: no core dump ... May 29 07:09:08 wall /bsd: sk0: watchdog timeout I have had similar problems with other machines running OpenBSD 3.6, 3.7 and 3.8. I do not know if it helps, but what is common in all these cases is Intel/Pentium IV and D-LINK DGE-530T. I only used brand new NICs and machines. On the 3.7 machine, it did happen so often that I decided not to use the NIC and switched to a on-board fxp NIC. The problem simply disappeard. This is just a small extract from the log files.

But the machine in question is not traffic intensive at all.

The NICs show as could you try this with openbsd 3.8? (there have been some changes in the sk driver for the 3.9 release) how long did the sk work before you got the watchdog timeouts? could you pass any traffic? reyk -- ___________________________________________________ Play 100s of games for FREE! http://games.mail.com/
