This sounds to me a

	kill (-1, whatever)

is executed by mistake on the host.
(Yeah, this sounds like a bug.)

Maybe the first argument to kill was supposed to be
a process ID, but the process id was somehow
-1 (because the value was returned by a failed
system call since such process was not found, etc..).

process 1 is usally init.

Hence I suspect that the sshd running with effective ID of
superuser was invoking kill() for process ID, -1, by mistake.
