What happened: with --cpu-manager-policy=static kubelet will panic when pause container lose during kubelet restarting What you expected to happen: kubelet can start normally How to reproduce it (as minimally and precisely as possible): 1,config kubelet with --cpu-manager-policy=static 2, Run a large number of pods on the test node 3,stop kubelet use command: 4,kill and remove all the pause container like this: ! 5,start kubelet use command: and then kubelet maybe panic, log is : Anything else we need to know?: When we actually encountered this problem, only one pause container was lost. In order to reproduce this bug, I deleted all pause containers.
