Running tail or grep on a large (>10mb) file via NFS from another 2.2.6 machine (with an Intel 100+ too) will simply freeze the tail or grep process, and it won't die. ps shows the process in disk wait, even though other operations on the mount will be fine. When I replace the Cisco with a 10 megabit hub, the cards drop to 10 megabit and half duplex, and there are no nfs problems. Cisco said they had some internal docs talking about problems with the Intel 100B cards running 100 megabit, full duplex, that were cleared up with the 100+ cards. Intel was completely useless. I'm wondering if there is perhaps a problem with the fxp driver in 2.2.6, or some weird issue with the Cisco. I don't have another 100 megabit switch laying around, and I really wouldn't want to have to switch from the Intel cards not knowing what the problem is. All that Cisco could suggest was different cards or a sniffer to look for more clues. Any ideas? This seems pretty weird. Thanks. -- Scott M. Drassinower scottd@cloud9.net Cloud 9 Consulting, Inc.
