The update to 3.7.3 is precisely what fixed that problem, but the next update might have an extra fix to prevent a rare situation that could still cause this.
The real reason why you see this, it's because GSX is far less likely to crash in flight now, because it does a lot of extra paranoia checks against bad data coming from the Navdata API, and since it's not crashing anymore, it's not even auto-restarting, which would always reset the services (of course).
