I've still not determined whether this is an optimizer issue, but we have now seen this problem across all 6 server in our Ubuntu QA cloud; this appears to be a problem that builds up over time - the tenant that sees this first is our automated testing account which creates/deletes alot of instances over time. Across all nodes I see: 2015-01-08T13:36:07.822Z|80336|dpif|WARN|system@ovs-system: failed to flow_del (No such file or directory) skb_priority(0),in_port(4),skb_mark(0),eth(src=ae:c4:93:ba:85:3e,dst=33:33:ff:5f:c4:32),eth_type(0x86dd),ipv6(src=::,dst=ff02::1:ff5f:c432,label=0,proto=58,tclass=0,hlimit=255,frag=no),icmpv6(type=135,code=0),nd(target=fe80::8412:d1ff:fe5f:c432) message alot; which is related to https://github.com/openvswitch/ovs/commit/3601bd879 which we don't have in the 3.13 kernel for trusty. I'm wondering whether this is related - the stacktrace relates to flow misses and has a large parameter list in the handle_flow_misses call. The optimized code may just be obfuscating the actual problem. - -- James Page Ubuntu and Debian Developer james.p...@ubuntu.com jamesp...@debian.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBCAAGBQJUrvNhAAoJEL/srsug59jD7SgQAM5FC8Sfg7Uob11fx5Ik8458 UwiLHMHq93eT9Tp4YQXXpjThY4EioT9LWWcJtidGOAAWw4Zc7BsMB8KL7v5aclno dLogpAQNRd+dt/trAXchkOIqCWEDhXvEmbusJJkEGktk3ZOPHayJjjTsJ7eX+V4s JH9xuDsfqDlOiRpFhwCr1xEwlKZNqB3aKeqj9ulMgiQviy/GC3JcWDcVKOogo8Tr LUwuiotjJkPDuwjIhu7TO6uRpPE1N15JLZnhwGzlBFXNGI5gWK+PQzDcVANi+B6x 2mDXDIq1QK8lhABBcjc2P2cAwmQEZ+TnHdn0E9ZlIUdWkRNMQVuVJPWJh6LK+gkO ZznyAFfUhL+qbt7znLB/NXA/fAFHLXjehTOYLGIvQgcbEU2tqy/ENfpNy1UPhsRs 6hu5FpTuNqUz5IdGqb8EnI6MANR8P2sNv9zk90/eD2TveGGN6GdKXCW1CZ2JYBmc /iIdycLiKpsT0Ugcvf80Xp0nrSATWYtVNRlaTE/yzEHldwFb0Th/hSMsVpWw0bnS voaxRwiv4EgiwVGbu2WNR6AufC1a01XYtbQJCubMlzpiVv4T6zABHzbJe36HLpTi sz+8jZFAPBIylOHZz+cwPmBNownxpNKE83ZvqrhPqLSNI90jmCekWhzjiqvVMnP/ HXrLgyqqJsyEpi4FXo8w =3qsm -----END PGP SIGNATURE----- _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
