You'd see pretty much the same symptoms in that case. I don't know what kind of HW you have. Just to clarify a little - the queues are limited to 50 entries IIRC. Once a queue fills up you start seeing the "No buffer space" message. An output queue should only fill up if the packets aren't going out fast enough or at all. --- Gary Jennejohn / garyj@muc.de garyj@fkr.cpqcorp.net gj@freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
