Say 1 in 10 times, 1 in 5, 1 in 20? hm, I can't reproduce issue with empty files, but I see another behavior: on every 3-4 runs it does not collect lscpu, lspci and proc_cmdline files for some of worker nodes: # ls -la nodes/worker-0 total 96876 drwxr-xr-x. 2 root root 81 Jul 2 09:48 . drwxr-xr-x. 10 root root 159 Jul 2 09:48 .. -rw-r--r--. 1 root root 198 Jul 2 09:47 lscpu -rw-r--r--. 1 root root 36451 Jul 2 09:47 lspci -rw-r--r--. 1 root root 347 Jul 2 09:47 proc_cmdline -rw-r--r--. 1 root root 99155968 Jul 2 09:48 worker-0_logs_kubelet # ls -la nodes/worker-1 total 110368 drwxr-xr-x. 2 root root 35 Jul 2 09:48 . drwxr-xr-x. 10 root root 159 Jul 2 09:48 .. -rw-r--r--. 1 root root 113016832 Jul 2 09:48 worker-1_logs_kubelet can't reproduce it after 700 runs, bug fixed Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
