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. ---greg Greg Fausak August.Net Services, LLC greg@august.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
