PollingObserver silently dies when SMB mountpoint is unavailable for some time

[cmantsch]

I am observing a mounted SMB share using a polling observer (SMB share on Windows Server, Observer on Ubuntu 24.04).

When the Fileserver goes offline for a few minutes, the PollingObserver does not emit any events anymore after the Fileserver comes up again. Only way to recover back to normal has been to restart the application.

Is there a way inside watchdog to recover, maybe some exception that can be handled?
