i had the same at that time, but not enough to dismount, its 22:48 for me now, so past the window it has dismounted all previous days.
It would seem like today is the first day in over a month that i havent had any dismounts, i REALLY hope this means the issue was at google and is now resolved.
i also switched to using the latest beta builds around when i posted this thread, i also noticed performance seemingly being much better. i assume something changed in the way I/O works?
