After Updating from 3.0.0 to 3.0.1 it works all normal. But after some hours i can not send some command to items (over all bindings and over basicUI and mainUI). I can switch an item, but when I reload the page it is on the previous state and the thing itself also receive no command (nothing happens).
After a restart it works, but only for some hours.
I see nothing related to this problem in openhab.log and event.log.
