Sudden crash when WLL-device is in disorder #19

Closed hoevenvd closed 3 years ago

hoevenvd commented 3 years ago

Driver crashed suddenly. In the log there's no clear reason. I run this driver in my production environment. A similar driver (from Drealine) is running in my development-environment, and crashed at the same time and with the same error report. So, there must be something. with my WLL-device at that particular time, that caused this driver (ant the driver from Drealine) to crash (and was not properly caught as an exception).
