Maybe this errors might be interesting - I'm not keepalived expert but someone might tell us whether keepalived terminates itself between process.active and process.disable()

Also note that keepalived is actually 22313 [1] while we send sigterm to 22312 [2] which is likely a parent process of keepalived (maybe sudo, maybe rootwrap). I'm investigating how ProcessManager makes sure the actual child process is written to pid file so it doesn't contain wrong values in case machine is too slow and children weren't born yet.
