Please note that support for log level "debug" has to be enabled at
compile time. Since this pops up every once in a while, it might make
sense to change that. This would introduce a couple of additional
function calls all over the code but I would not expect that to matter
all that much. Any comments about that? Florian, what do you think?

Anyway, Domagoj, do you see any other error messages before that? If the
plugin does not report any error at all in that case, I'd consider that
to be a bug. That message tells you that, for some reason (hopefully to
be found in the log as well), querying 'some_device' failed. The daemon
then delays further queries by an increasing amount of time.
