I have a Unix server that has started rebooting every few minutes. I tried to trace the source of the problem by logging the process tree at the time reboot is called, as described by this question's answer.However, I don't understand where to look next.The log contains these lines (among many others):root         1     0  0 16:49 ?        00:00:00 /sbin/initroot      2894     1  0 16:53 ?        00:00:00 /bin/bash /sbin/shutdown -r now Control-Alt-Delete pressedTo me, it looks like the server's startup process is calling a reboot with shutdown -r. In the system log, all I see is this line:sshd[2433]: Received signal 15; terminating.Also, this is an Amazon Web Service Unix instance that only allows connections from my IP address. It's also protected by a private key.What are the next steps I can take to find the source of the problem?
