[Ubuntu 16.10] System slowdown due to increased memory usage upon resume

🤷🏽‍♂️ Current Behaviour

When resuming from suspend (not checked after hibernation), one of two pb-for-desktop processes increases its memory usage until fully taking up all available RAM.

🎯 Expected Behaviour

Not to leak memory this much (duh? 😄)

👟 Steps to Reproduce (S2R)

1. Suspend machine
2. Resume machine
3. Wait and see as PB for Desktop eats your RAM away! App Version v3.8.0 Installation Type deb file install Operating System Ubuntu GNOME (16.10) 64-bit

I’m testing regularly, updating as the updates go… It does seem to be random though, as not all resumes yield memory leaks.

So after a while of random memory leaks, I might have found that I was mislead before - memory leaks also randomly happen on network status change. And since I use my laptop and suspend it before moving, there might be a time where the computer loses network while it reacquires wi-fi signal. This is what I think actually trips pb-for-desktop and make it start building up memory onto infinity.

This might also be why the leak happened with my computer - as the WiFi dongle I use doesn’t have an Ubuntu driver, I’m stuck sharing internet with my phone through USB. Unplugging it causes a network change - and the rest is history.

Further evidence towards this is the fact that I have carefully avoided any ad-hoc network change on my desktop PC and I did not see any leaks in a while now.

But, it remains relatively random which makes me think there is even more to it than that…
