Doh, missed the comment for a long long time. I've check /var/log/messages, dmesg, kern.log, but it didn't contain any related information. messages is empty except for "Aug 17 02:11:13 frontend01 -- MARK --"'s, kern.log has two lines of TCP: Treason uncloaked, but it's unrelated, wrong IP, dmesg ends just after boot with [ 78.195005] ip6_tables: (C) 2000-2006 Netfilter Core Team.
Attached is the lspci output - it's an almost standard Dell PE1950 III configuration; although I don't think it's a hardware issue, that can't make netstat -an list duplicate src-port-tar-port tuples. As for the tests with a new kernel - the first thing I'll have to do is to write a script to trigger it on demand. The servers were ordered in a pair, one production, one testing, so I could try the new kernel. But I'm not sure about installing karmic alpha - while it has a kvm-over-ip card so a reinstall isn't completely impossible, that DRAC5-terminal is a pain to use and we'll lose the ability to try out 8.04 update packages on the spare machine until we revert the configuration. So the plan is: make port crash script, trigger bug. Install new kernel, if fixed: search for patch, wait for backport / upgrade to 9.04 and see if that helps, if not fixed: try to trigger it on different hardware within arms reach instead of over ip, much more debugging required. ** Attachment added: "lspci output" http://launchpadlibrarian.net/30404995/lspci.txt -- tcp duplicate source port https://bugs.launchpad.net/bugs/403750 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
