I'm trying to remember if we had to bump any of the sysctls to actually reach 1024 containers, I don't think any of the usual suspects would be in play until you reach 2000+ Alpine containers though.
If you do run out of some kernel resources, you can try applying the following sysctls to get you past that: net.ipv6.neigh.default.gc_thresh3 = 8192 net.ipv6.neigh.default.gc_thresh2 = 4096 net.ipv6.neigh.default.gc_thresh1 = 1024 net.ipv6.route.gc_thresh = 8192 kernel.pty.max = 65536 kernel.pid_max = 2097152 fs.inotify.max_queued_events = 1048576 fs.inotify.max_user_instances = 8192 fs.inotify.max_user_watches = 524288 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567557 Title: Performance degradation of "zfs clone" when under load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1567557/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
