Stefan, regarding comment #12 A few of us have noticed that recent changes in the testing framework are causing neutron network resources to not be deleted (I filed bug 1274410 this morning, but we have known about this for almost a week unfortunately).
A side effect is that this leaves a rather significant amount of processes running in namespaces. I don't know if this might be a possible cause for this particular failure. I will try and apply crashdump to the dev machine which I'm using as a repro enviroment. On this machine however, I've not seen the failure so far. I won't be however able to do this in the next few hours, so if somebody else from the neutron team wants to take over, please go ahead. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1273386 Title: Neutron namespace metadata proxy triggers kernel crash on Ubuntu 12.04/3.2 kernel Status in OpenStack Neutron (virtual network service): New Status in OpenStack Compute (Nova): New Status in “linux” package in Ubuntu: Incomplete Bug description: In the past 9 days we have been seeing very frequent occurences of this kernel crash: http://paste.openstack.org/show/61869/ Even if the particular crash pasted here is triggered by dnsmasq, in almost all cases the crash is actually triggered by the neutron metada proxy. This also affects nova badly since this issue, which appears namespace related, results in a hang while mounting the ndb device for key injection. logstash query: http://logstash.openstack.org/#eyJzZWFyY2giOiJcImtlcm5lbCBCVUcgYXQgL2J1aWxkL2J1aWxkZC9saW51eC0zLjIuMC9mcy9idWZmZXIuYzoyOTE3XCIgYW5kIGZpbGVuYW1lOnN5c2xvZy50eHQiLCJmaWVsZHMiOltdLCJvZmZzZXQiOjAsInRpbWVmcmFtZSI6ImN1c3RvbSIsImdyYXBobW9kZSI6ImNvdW50IiwidGltZSI6eyJmcm9tIjoiMjAxNC0wMS0xNlQxODo1MDo0OCswMDowMCIsInRvIjoiMjAxNC0wMS0yN1QxOToxNjoxMSswMDowMCIsInVzZXJfaW50ZXJ2YWwiOiIwIn0sInN0YW1wIjoxMzkwODUwMzI2ODY0fQ== We have seen about 398 hits since the bug started to manifest. Decreased hit rate in the past few days is due to less neutron patches being pushed.
