Game Freezes Randomly w/ "Watchdog Wakeup"

Hey everyone,

We recently noticed when running our game on Android devices that the game will sometimes freeze and display the following message in the debug console:

Watchdog wakeup : 1.12s has past without activity
[Many, many more similar lines]
Watchdog wakeup : 200.99s has past without activity

One time, I left the app running like this for a few minutes, and the game eventually came back to life, so the app isn’t hard crashing. Does anyone have ideas as to what this behaviour/message means? It just started happening recently, but I can’t think of any changes to the build that would have caused the issue. When it occurs, we aren’t loading a level or anything. Could it maybe be garbage collection - and if so, why would it take so long (several minutes)?

Thanks!

I’ve read somewhere that when an app requires extra memory, it will need to wait until Android provides it by shutting down other background processes. I’m not sure if this is the issue, but it kind of sounds like it to me.
