I want ideas to trace which app is rebooting my android

Question

Some process is rebooting my phone every time it connects to Wi-Fi. I thought of connecting it to the PC and do an strace in init or zygote or the system server, but I don't know what to look for in this traces.

Can you guys suggest some ideas or explain which are the system calls used to reboot/shutdown the Linux kernel?

I just did a logcat and got the result below. If you guys do a ctrl+F there is a "reboot" in the middle of the text:

I'll try another logcat, but from android terminal so it will stop when the system shut down
