Hi Dan, We run a bunch of instances both on AWS and GCP, and we run a significant number of containers on both. We've only ever seen this problem on GCP and never on AWS (it's baffling!). The kernels are as- close-as-possible and the rest (Ubuntu version / Docker version / etc) are identical. To answer your questions:
-what release are you using (trusty/xenial/zesty)? Xenial -what kernel version are you using? 4.13.0-1008-gcp -do you have specific steps to reproduce the problem? Unfortunately we don't. It just happens on its own after 1/2 weeks. The following shows in dmesg: [1015401.681728] unregister_netdevice: waiting for veth251ecfe to become free. Usage count = 1 [1015411.761772] unregister_netdevice: waiting for veth251ecfe to become free. Usage count = 1 [1015421.841740] unregister_netdevice: waiting for veth251ecfe to become free. Usage count = 1 [1015431.953729] unregister_netdevice: waiting for veth251ecfe to become free. Usage count = 1 etc etc We've tried a few things including upgrading kernel and disabling IPv6 to no avail. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1711407 Title: unregister_netdevice: waiting for lo to become free To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1711407/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
