I mean instead of running "wine yourapp.exe" you run "WINEDEBUG=+relay wine yourapp.exe" (without quotes of course. You will see that there are pairs of calls and answers. look at the last lines if every call has an answer (usually the answer has a part of the number of the call within it). If not, that's your problem and not MEM_TYPE_WATCH. Look at the last lines. If there is something abnormal in the last lines, maybe one of the developer will ask you for more information but to see if not the last call is hanging, the last 10 lines are enough.
