Got many NetworkManager warnings at boot

my system log fills up with these warnings.

Any ideas?

I can’t help with the actual problem, but the format of the error basically says that PID 6126 is not running, and something tried to look at the status of the PID. Perhaps the process is in some way defunct and the application doing the query does not handle this well. Sorry, I have no idea on what NetworkManager is doing at this moment, but if you have any special network settings (wired or wireless), then it is probably related.

Thank you for your advice.

I do disabled wifi.
I did these things.

  1. sudo nmcli radio wifi off
  2. sudo rfkill block wifi
  3. “rfkill list” or “nmcli device wifi list”
    Nothing is displayed in the list.

I wonder why get errors about wifi.

That would make sense. If WiFi is disabled and blocked, but there is still some mistaken monitor of WiFi checking on its status, then that status check might fail in this manner if the status check believes that process ID is running. The real question at that point is how the checking program got that PID. In theory there would be no PID unless something ran a program or command producing the PID.

I can think of an example that perhaps some software is running a program and getting its PID, but failed to note that the program actually failed in some way (poor return value checking). It’s all just general guesswork though since we’d need to know not only what the PID is, but also what created the command to start the PID. Very likely every time this runs it will be a different PID.

If you do happen to see this again, and the PID continues to be available, you might examine the following to find out more about the PID (I’m using the old 6126, but you’d need to substitute for whatever the PID is at the time):

  • `ps aux | grep ‘6126’
  • This is the part failing, but seeing an error might be useful:
    cat /proc/6126/status
  • cat /proc/6126/loginuid

Notice in “status” that it might show a “PPid: ...” (unless of course it fails like in the log). This could be important, as it is the parent PID which started the existing PID. If for example the PPid shows as “1234”, then you’d also want to know:
ps aux | grep '1234'

None of this directly solves the problem, but it might show where the problem originates.
