   This looks like race conditions with stopping / uninstalling

   @andrewkolos - is there another bug tracking this? Maybe this is a driver race condition?

   I am not personally aware of one

   There is nothing I can do about this. This hasn't failed in the last 200 runs, so closing: https://ci.chromium.org/ui/p/flutter/builders/prod/Linux_mokey%20large_image_changer_perf_android?limit=200

   Coming back to this just to dump info: this is clearly a race condition. The memory info (dumpsys meminfo) is not being run directly by the test. I believe it is devtools.

   In both cases all tests pass; but some task in running / logging.

   Good condition:
