I had a similar problem with a etinc.com board. We currently have
6 T1 lines with 600+ frame DSL customers running on freebsd with
two 4 port etinc cards. We experiences reboots, sometimes after an
hour, sometimes a few days. It was due to exhaustion of mbuf
resources. Try entering the command:
netstat -m
and you will see something like:
389/2080/65536 mbufs in use (current/peak/max):
385 mbufs allocated to data
4 mbufs allocated to packet headers
319/1946/16384 mbuf clusters in use (current/peak/max)
4412 Kbytes allocated to network (16% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
If your mbuf clusters exceed the maximum available then the
machine reboots! I fixed the problem by adding the line:
options NMBCLUSTERS=16384
into the conf file and then rebuilt/installed the kernel.
We haven't had a problem since increasing the default NMBCLUSTERS
value, on our machine it was 1024.
