ZigBee inconsistency

recently i added a HUSBZB-1 USB Hub which for 3 weeks was great, but recently all the devices quit responding complete for 36 hours, after a few reboot it appears to be working again but not consistency. ( When you turn a light on it will flicker then stabilize, same thing turning a light off. also occasionally there a 2-3 sec delay for action, the console show the change it just not being received by the zigbee device.

Attached it a debug snippet

any help would be great appreciated

Try the log viewer to see if there is anything obvious.


Thank you I will give it a shot
