Suddenly indigo (or z-wave stick) "forgets" device commands

Hi, since the update to 7.2 a year ago I'm facing somewhat strange behavior of Indigo:

Commands which normally worked get stuck and throw an error in the log such as:

Z-Wave Error device "038 - late night light 2" does not support off command
Z-Wave Error device "038 - Lautsprecher 2" does not support off command
Z-Wave Error device "038 - Nachttischlicht 2" does not support off command
Z-Wave Error device "038 - Relay Switch 4" does not support off command
Z-Wave Error device "038 - projektoruhr" does not support off command
Z-Wave Debug SENT setMultiLevelValue: 01 0A 00 13 27 03 26 01 00 25 5E 9E

of course these device supports the off command!

I had it also with a thermostat and some Fibaro switches. So it seems to be independent on the device type. I can solve it by re-sync the device. Nevertheless I get a bit nervous when the system kind of "forget" its basic functionality.

Last time this happened, before I had the z-stick disconnected to locally pair to a devise and then reconnected again.

I also more often see the Beachball which pauses the actions and alter the system unresponsive. I saw "canceling plugin" in the status line but cannot find out which plugin may cause the problem.

Any thoughts on this I appreciate.

I think there are going to be clues earlier on in the Event Log files that show what is occurring. What are the errors logged before (earlier) then the ones you pasted above? Note they might be in the previous day's log file.

Matt, I will check..... how can I access the old log files?

There is a button on the top of the Event Log window that will show (in the Finder) the logs folder.
