[Android Q&A, Help & Troubleshooting] FailSafeNow:
Something is eating up my CPU and making my tablet run hot. And I don't know how to fix it. I looked with 3C Toolbox to see what's using the CPU, and it seems to mostly be multiple instances of /system/bin/app_process, which apparently belongs to the kernel. Well, shoot. If it were an app that were using up all the CPU cycles, I could just disable it. But what do I do when it's the kernel?

I looked in Amplify to see if I could find any clues. The one thing that really seems suspicious is com.google.android.gms/.chimera.GmsIntentOperatiomService. I feel like it should not be startinging that many thousands of services. But what can I do about it?

Here are some logs from various apps that may help us get to the bottom of this. Any help is appreciated.
