I've run the related patch twice, and the kernel bug was hit even with SIGTERM rather than SIGKILL.
I think this kind of confirms that "failure to become ACTIVE" error is related to issues while terminating metadata proxies and dnsmasq instances. -- 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.
