Yes I tried the tests on non-RT kernel and the issue was not reproduced with 14 hours of testing with docker running kubernetes. I also tested with the test case mentioned in moby github issue and the kernel freeze was not seen. Config file is https://paste.debian.net/1039104/ root@debian:~# uname -a Linux debian 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u3 (2018-03-02) x86_64 GNU/Linux > Can you send your full config?

Config file is https://paste.debian.net/1039103/ (output of 'grep "=[y|m]" config-4.14.59-rt37') This issue was reproduced with 4.9.0-6-rt-amd64 kernel also. root@debian:~# uname -a Linux debian 4.14.59-rt37 #1 SMP PREEMPT RT Fri Aug 24 00:31:29 UTC 2018 x86_64 GNU/Linux Below are the steps to reproduce the issue, Install docker using, curl https://raw.githubusercontent.com/rancher/install-docker/master/17.03.2.sh | /bin/bash Run "for f in $(seq 1 10000);do docker run -it --rm ubuntu echo $f; done" consecutively in 3 terminals. The freeze/lockup occurs sporadically. The other test case is to run docker with kubernetes. Regards, Vignesh
