I think so. I still have this problem, where after a while zwave events stop coming up, and then I get a Queue Full exception error.
I connected another device and when this happened, I stopped seeing events from the other device as well, so I think this is a more general problem that is related to the zwave thread and not specifically to the HSM100.
I opened another thread for this issue here. @chris do you know what could cause the exception?
