<p>I am gettting this error in kubectl <code>describe nodes nodename</code>. I just did a google search but nothing useful found , what does this mean.</p>

<p><code>Failed to update Node Allocatable Limits "": failed to set supported cgroup subsystems for cgroup : Failed to set config for supported subsystems : failed to write 3783778304 to memory.limit_in_bytes: write /rootfs/sys/fs/cgroup/memory/memory.limit_in_bytes: invalid argument</code></p>

<p>Do I need to change some kernel settings using sysctl ?</p>

<pre><code>[iahmad@lxplus000 ~]$ kubectl --version

<p>It depends on the <code>kubectl/kubernetes</code> version: this was seen (and fixed) in <a href="https://github.com/kubernetes/kubernetes/issues/42701" rel="nofollow noreferrer">kubernetes issue 42701</a></p>

<p>1.6 should have been patched.
If this is not the same bug, the error message was also seen in <a href="https://github.com/kubernetes/kubernetes/issues/29166#issuecomment-315787325" rel="nofollow noreferrer">issue 29166</a>:</p>
