Oh, I should have explained better here. Re-spawn works, it's the (daemon) service that might misbehave/go unresponsive without crashing, i.e. HTTP backend stops responding to API requests but the server is still up. The job performs a "health-check" and restarts it if it doesn't get the appropriate response. A concrete situation where this could be of use is for logs.guix that occasionally stops recording. > > You can send messages to the bitbucket with: > > (parameterize ((shepherd-message-port (%make-void-port "w0"))) > …) Thanks! I'm still curious as to exactly what/which lines cause shepherd to output the lines. Cheers, Bruno
