Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=ISO-8859-1 Content-Transfer-Encoding: 8BIT Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi, all. I've got two FreeBSD boxes (3.1-R) working as routers, one with two 4-port ZNYX 10/100 ethernet cards and the other with one of those cards. The cards have DEC chips (21140A). The routers are working perfectly, but from time to time I get the following messages: de0: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) de1: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) What do they mean? Everything seems to be OK, but I'd like to know wether I have to worry about this or not. TIA, Pedro. -- ------------------------------------------------------------------- Pedro José Lobo Perea Tel: +34 91 336 78 19 Centro de Cálculo Fax: +34 91 331 92 29 E.U.I.T.
