Title: When sshd exits because of a bad configuration, upstart claims the job is in "start/running" with no PID Status in upstart package in Ubuntu: New Bug description: Reproducible on 14.04 and 14.10 In ssh's upstart config file, "expect stop" is used to signal upstart when sshd is ready to accept connections. If the sshd config file is broken, sshd terminates before it sends SIGSTOP to itself and this seems to confuse upstart, such that it thinks the ssh job is still in start/running state (with no associated PID.) In addition, I have another upstart job set to trigger on "start on stopped ssh RESULT=failed" which does _not_ trigger in this situation. If I comment out the "expect stop" stanza from ssh.conf then the sshd process properly ends up in "stop/waiting" and my other job triggers properly. Here is the DEBUG output from init when I start ssh with purposely broken sshd_config file Jul 19 16:47:43 patrick-vm kernel: [956961.180770] init: ssh goal changed from stop to start Jul 19 16:47:43

is to have an upstart job trigger in the event that sshd_config is broken and do something helpful , e.g. start another sshd on another port with a known good config so I can get back into the box to fix the problem.
