I tested the pre-built binary of the latest version of runc (by just replacing /usr/sbin/runc) and I was able to go to 400 pods on a single test node. This new version was released today.
``` root@node0:~# runc -v runc version 1.0.0-rc94 spec: 1.0.2-dev go: go1.14.15 libseccomp: 2.5.1 ``` https://github.com/opencontainers/runc/releases I tried the pre-built binary of runc 1.0.0-rc93, and I was stuck to 164 pods again with "code = DeadlineExceeded desc = context deadline exceeded" error: ``` root@node0:~# runc -v runc version 1.0.0-rc93 spec: 1.0.2-dev go: go1.14.14 libseccomp: 2.5.1 ``` The changelog for 1.0.0-rc94 contains this line that could match: runc init: fix a hang caused by deadlock in seccomp/ebpf loading code (regression in rc93, #2871) The version 1.0.0-rc92 was working fine too. ``` root@node0:~# runc -v runc version 1.0.0-rc92 spec: 1.0.2-dev ``` Please upgrade to version 1.0.0-rc94 or downgrade to 1.0.0-rc92. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927219 Title: context deadline exceeded: unknown in containerd with latest runc version To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/runc/+bug/1927219/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
