Is anyone else having problems with WISM based controllers unexpected crashing? I have an open tac case and I did get a replacement module for one switch, but I am not confident that the problem will go away. The system is not logging anything to the crash files, and it took me a while to convince tech support to replace the hardware. They kept saying it was some undefined software bug. I am running version 4.2.112 code. I have that same code running on several standalone controllers and it's been very stable. I was wondering what everyone else's experience has been with this hardware.
