I did notice that my linux wallet did crash yesterday and had to be restarted.  It has been pretty stable running on my orange pi over the last few months though.  The windows wallet seems to be fairly stable once it is synced, although when it is loading blocks it does seem to crash.  My biggest complaint about the windows wallet is that it seems to use a lot of cpu resources and stops responding/hangs up/lags.

Mining on this coin is currently over 540MH/s so it is far from dead.
