To amplify Bogdan's statement: this means that some other part of the system is misbehaving. Even slow machines can handle full-rate traffic from a 3c905C if nothing else is going wrong. > Saying the the 3Com card/driver is at fault is not realistic - as > you can find through search engine results, these network cards are not > the only ones giving this message... Quite the opposite: the reason that other drivers(*) aren't reporting the problem is that - they don't limit their resource usage to prevent other problems, and - they don't check for external problems. Most network driver messages are reporting external problems that have been detected, not internal software failures. (*) It's primarily network drivers from my standard structure that do this limit check. -- Donald Becker [email protected] Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 _______________________________________________ vortex mailing list [email protected] http://www.scyld.com/mailman/listinfo/vortex
