> h2. STR:
> # create directory 
> # change current dir to this directory
> # remove directory
> # run ambari-server restart. It will complain that could not perform getcwd and fail.
> # Check ambari-server PID file:
> {code}
> # cat /var/run/ambari-server/ambari-server.pid 
> 1
> {code}
> # The 1 is a PID of an */sbin/init process*
> {code}
> cat /proc/1/cmdline 
> /sbin/init
> {code}
> # Try to restart ambari-server. It notices that old process (INIT) is running and tries to kills it. As a result, INIT process does not die, but SSHD and probably other services are killed, active login sessions are terminated.
> # Now host is not available over SSH and requires physical access
