Back in October, I complained in the current-users thread "ipnat
is broken in 2.0RC4", that a -current/i386 based firewall kept
freezing, and unfortunately I found no hints - no sign of anything
special happening when it happened. To quote:

  So, replacing the -current/i386 code of 13 October 2004 with code
  from 15 October 2003 has "fixed" this firewall/nat box. On Monday
  it will be 3 weeks that it has been up continuously.

In fact, that box has been running 2003 code ever since with no
freezes. (same box, network, etc.)

The reason this thread seems connected: the firewall contains 3
3Com 3c905C-TX 10/100 Ethernet with mngmt (rev. 0x78) cards (ex+exphy)
Possibly a link?

Cheers,
