Taken from https://xamarin.desk.com/agent/case/33574 :
I don't have a clear repro for this, whenever I debug Infinite Flight with
VS 2012 on any android device, VS goes crazy on the memory usage and stalls
for a minute every time I want to stop debugging (shift/F5), and very often
when the debugging session is running.
Memory sometimes cycles from 300MB up to 1.0GB+ then back to 300MB every
couple of seconds, and CPU usage is 100% on the core VS is on.
I have no clear repro, just thought you guys might be interested and could
point me to something I could do to help.
Just tried now, it starts by oscillating between 270 and 380MB+ when the
app is running. When stopped it, it went up to 533MB, then as I typed, went
down to 322MB.
Second run, memory goes from 340 to 600MB in a couple of seconds, then goes
down to 250MB... Not sure when it starts going to 1GB but it seems to be
I think I've seen the hangs mostly when I was outputing tons of log that
was shown in the Output window. Maybe it's related... When log is shown,
I've also had issues using VS, it hangs frequently and I have to pull the
device off the machine to make VS react.
Here's the complete log of the about box.
