I can exclude this: - The statistics do not show any 'loss of carrier' (mentioned above) - On the same hub's, there are some highly available financial applications and web-servers. If there would be that sort of problem, I'd surely noticed. - For some other reason, we changed the hub and cabeling, and the problem still exists... >> I remember to have the same problem with another box running 3.3 >> generic (other hardware...) - so I am wondering if the driver >> might be somehow broken. > >But if it was a driver problem, the problem would show up on >both interfaces, right? Yes, and inbetween I can confirm: The problem occurs on both interfaces; the chance that the problem occurs is slightly higher on the interface with the higher network load. To sum up: As the very same problem occurs with pretty different hardware, I really think there's something wrong with the cooperation of the ep-driver and 3com 509 - maybe the driver, maybe some design error on the network cards... So if sb says: 'No probs with ep driver and ne2000 cards', then I think we have to ask 3com... ;) -- Daniel Zuck * eMail: daniel@dan-up.de * Faxmail: +49-69-823 789 49 Voicemail +49-69-823 789 50 * ... and I've also got snailmail! :) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
