I have 2 node LXD with version 5.5-37534be in cluster mode in OS ubuntu 20.04 and kernel 5.4.0-125-generic,
one of the node hung every day, i check kern.log and found memory Cgroup out of memory
i saw a lot of logs oom in my container
i set my container memory limit 4GB and my mistake cause oom in the container, but my host memory usage is low
can oom in container cause hung on server host?
