It was: $FreeBSD: src/sys/kern/uipc_mbuf.c,v 1.51.2.20 2002/08/12 22:09:12 luigi Exp kern.ipc.mcl_pool_max: 0 Problem looks like a kind of magic: switch---switch | | | A B C Host A is pantagruel, Athlon XP on VIA KT333 Soltek MB. It is connected using Compaq/Intel NIC. Runs fresh GENERIC 4.6-STABLE. It crashes. Subnet a. Host B is gargantua, Celeron on VIA694T Asus MB. It is connected using 3Com 905B NIC. Runs 4.6.2-RELEASE. Subnets a, c. Acts as a router beetween A and C. Host C is Athlon on SiS735 ECS MB. It is connected using Compaq/Intel NIC. Runs fresh GENERIC 4.6-STABLE. Subnet c. When I try to fetch something big from A to B, A crashes. When I try to fetch something big from B to A, A crashes. When I try to fetch something big from A to C (via B), A works fine. When I try to fetch something big from C to A (via B), A works fine. That's interesting. When I try to fetch something big from B to C, C works fine. When I try to fetch something big from C to B, C works fine. So, I have machine C. It runs 4.6-STABLE and has no problems with fxp interface! How-To-Repeat sections in kern/42260 seems to be wrong, I can't reproduce this problem on other machine with fxp interface. I have machine A, it runs 4.6-STABLE and crashes when there is heavy traffic on fxp interface AND traffic goes directly to B. This fxp interface was replaced with identical Compaq/Intel NIC, nothing helps. When traffic from A goes to B and then to C (meens this is A-C connection and B acts as a router beetween them), machine A is not crashing. (?!) There are no compile optimizations. I would suspect some hardware fault, but there is one thing: When I downgrade A from 4.6-STABLE to 4.6.2-RELEASE, A has no problems and everyting works fine. -- Paweł Małachowski, mailto:pawmal#freebsd,lublin,pl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
