I am using a freebsd box as a gateway in order to throttle down bandwidth for some particular traffic. The box freezes under high load and the only way to recover is through a power cycle. The crash does not generate any logs, but I have ruled out hardware causes. I can repeat the lock-out with 2 different hardware and with xl(4) and dc(4) NIC's I am suspecting a problem with DUMMYNET's PIPE and QUEUE. I have collected all the config information about the machine with a small script that helps in crashing the box after a few minutes of alternating the dummynet pipe's size. http://www.geocities.com/dummynetus/ipfw.txt In summary, I have tried the following: - Boost maxusers to 128 - Boost NMBCLUSTERS to 10240 - monitor netstat -m gives normal readings even before freeze To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
