We develop a vr game use Unity, explore exe to run on win10.
after running ahout hours the game progess hang.cpu 30% (4 cores)
it looks like an infite loop, but...
1.use dnSpy to debug , we tried to find error from managered c# stacktrace.but all thread looks like correct.(main thread c# update method can not enter, it looks like suspend)
2.windbg break serveral times,

at the moment we find memory usage reduce from 390M to 20-30M.
i can not know what happens, someone has same experience? what's the reason of memory useage reduce?more than 5 threads(contains main) was running WaitForSingleObjectEx for the same object(address 0xe6eb5a8f)
