Why Does Containerd’s PLEG Relisting Stall at Node Startup and How to Fix It

When replacing dockershim with containerd, we observed that pods take over a minute to start because the GenericPLEG Relisting operation stalls for more than 30 seconds during node boot, caused by containerd’s UpdateContainerResources holding a bbolt lock and intensive image pulls; the article explains the root cause and provides a fix using the overlay volatile mount option.
