I’ve just tested the new Systeminfo 2.0 binding and it is logging a lot of those errors:

The problem only occurs in the process channels. Those channels try to get infos from PID 0 as default, but this doesn’t seam to work on my machine. (BeagleBone Black) What could be the problem?
I also would like to get the process infos from the Openhab PID, but I can only set a static PID in the configuration. Is there a way to configure the channels to always get the values from the Openhab PID?
