checkservices: Error:: Unable to read maps file of dropbear.service for pid XXXXXXX. #48

For dropbear the checkservices script seems unable to pickup the correct pid for the service.

It's because when you ssh into your server with dropbear, the client session will run in the same cgroup as dropbear.service. So in this case checkservices does not only check broken maps files of the dropbear daemon, but everything running in its cgroup, including all user commands. I don't know why it gave the error, probably some user process exited before checkservices managed to check the PID in the loop. Note that if you restart dropbear.service, all sessions will be terminated so this is probably not what you want anyway.

I don't see anything actionable. Closing.
