Hello, time to time I get following messages in kernel log: Sep 29 23:19:15 castle kernel: eth0: first available media type: MII Oct 2 13:09:53 castle kernel: TCP: peer shrinks window. Bad, what else can I say? Oct 2 13:20:50 castle kernel: TCP: peer shrinks window. Bad, what else can I say? Oct 2 13:22:16 castle kernel: TCP: peer shrinks window. Bad, what else can I say? Oct 2 13:24:16 castle kernel: TCP: peer shrinks window. Bad, what else can I say? Oct 2 13:25:18 castle last message repeated 2 times Oct 2 16:14:15 castle kernel: TCP: peer shrinks window. Bad, what else can I say? Oct 2 16:14:49 castle last message repeated 12 times Oct 2 16:14:52 castle kernel: NET: 3 messages suppressed. Oct 2 16:14:52 castle kernel: TCP: peer shrinks window. Bad, what else can I say? Oct 2 16:16:42 castle kernel: NET: 1 messages suppressed. Oct 2 16:16:42 castle kernel: TCP: peer shrinks window. Bad, what else can I say? Last time after that system locked up. But I can't strongly say that above was reason... My system SMP2, 2.4.0-test7, eth - 3Com PCI 3c905 Boomerang, I am using iptables built-in into kernel with iptable_filter together. Average bandwith 1 Mbps. My questions would be following: 1. What could cause such messages; 2. How to fix that. 3. Could it be somehow related to iptables packet filtering rules (e.g. iptables -A INPUT -p tcp --syn -m limit --limit 1/s -j ACCEPT) and other tcp flags limits? 4. Now I have approx. 5% packet coalisions on eth0 interface, but I haven't any when eth0 wasn't aliased. What could it be wrong there? Thank You for answers. -- // Andrius Adomaitis Sistemu Administratorius // charta@gaumina.lt UAB Gaumina dizainas // tel.+370-85-54454 http://www.gaumina.lt - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
