[Galaxy S 4 Q&A, Help & Troubleshooting] lysaer:
Hi all

A couple of days ago I started experiencing constant reboots on my S4.

I downloaded Catlog and from what I can see there is something sending a SIG 9 which I assume as in Linux is a high level Kill command.

Here is a copy of my log.

I can see the Kill 9 Signal but am unsure what is causing it, I can post more of the log if needed.

thank you in advance
