I have been doing stress-testing on LXD at a freshly installed 18.04. The Linux kernel was the standard 18.04 kernel. LXD though was compiled from master, ZFS was also compile from master.
I performed the stress-testing by running the command lxd-benchmark --count 384 --parallel 24 This launches 384 Ubuntu 16.04 containers in batches of 24 containers. LXD does not run well on the mainline Linux kernel because I think some necessary patches have not been upstreamed yet. I plan to do more stress testing, and when I get the same issue, I'll run apport to retrieve information from the system to attach here. Obviously, when I deploy the server, I'll prepare it for apport beforehand. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781601 Title: Stress-testing LXD causes kernel hung in cgroups (cgroup_destroy css_killed_work_fn) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1781601/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
