It uses 2 3com 3c509 isa cards for this. It is routing a number of websites. And getting considerable load now (running on a Pentium 60Mhz, with 104M ram). natd is used as well, static mapping for 4 ips. The cards: Jan 12 17:01:10 genesis /kernel: ep0 at 0x300-0x30f irq 10 on isa Jan 12 17:01:10 genesis /kernel: ep0: utp[*UTP*] address 00:60:97:93:05:1c Jan 12 17:01:10 genesis /kernel: ep1 at 0x200-0x20f irq 11 on isa Jan 12 17:01:10 genesis /kernel: ep1: aui/utp[*UTP*] address 00:20:af:1b:9f:fe >Description: an 12 16:18:36 genesis routed[14626]: Send bcast sendto(ep1, 10.0.0.255.520): No buffe r space available Jan 12 16:20:37 genesis last message repeated 4 times Jan 12 16:25:37 genesis last message repeated 10 times Jan 12 16:25:48 genesis routed[14626]: sendto(ep1, 224.0.0.1): No buffer space availabl e Jan 12 16:26:07 genesis routed[14626]: Send bcast sendto(ep1, 10.0.0.255.520): No buffe r space available Jan 12 16:26:37 genesis routed[14626]: Send bcast sendto(ep1, 10.0.0.255.520): No buffe r space available Jan 12 16:28:37 genesis last message repeated 4 times Jan 12 16:33:37 genesis last message repeated 10 times Jan 12 16:34:03 genesis shutdown: shutdown by root: Jan 12 16:34:06 genesis syslogd: exiting on signal 15 It stops responding and routing at that time. The intranet is all NT Server (4 machines). One hosts about 60 websites, and is responsible for 75% of the network load. This was probably existing before, though the load, and the fact that the machine is "make worlded", new kern, and rebooted every 30 days, so it just wasn't long enough to present the problem. Since the machine has presented no problems for the last year, I seldom look hard. Will do more next time, and give further details then.. >How-To-Repeat: recurs about 1.5 days after a reboot. This started recently, when a large number of web sites were moved to the lan. ep1 is the intranet NIC. This is similiar to PR #15164, #12394, and maybe #9357 (all rl driver). >Fix: reboot was used, though there are better. I will look closer next time. This time around, had about 5 people phoning, and another 7 ICQing so extreme measures were taken in a hurry. Shutdown to single user has no effect. Will look deaper next time. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
