Erlang supervisor termination behavior
It is entirely expected, and it is expected because you are abusing the supervision tree capability. There is a hidden supervisor called the "application supervisor". Your application:start function is supposed to return a SINGLE pid which is to be monitored by the application supervisor. If that process crashes, the BEAM...
Erlang process termination: Where/When does it happen?
erlang,shutdown,otp,supervisor
It is quite nicely explained in the docs (sections 12.4, 12.5, 12.6, 12.7). There are two cases: Your process terminated due to some bad logic. It throws an error, so it can be in the middle of work and this could be bad. If you want to prevent that, you...
Error running bash script in supervisor [closed]
linux,bash,shell,debian,supervisor
Thanks Etan Reisner, I have already fix the problem, I will put it here so if anyone else have the same problem see why. The problem was so simple (as usual) I was reading the content of text files /sys/class/net/eth0/carrier and /sys/class/net/eth0/operstate to detect when the network cable was plugged...
Supervisor & Docker: How to exit Supervisor if a service doesn't start?
You can do this with a Supervisor event listener. Subscribe it to the event PROCESS_STATE_FATAL, and respond to the event by sending a SIGTERM to supervisord, which you are presumably running as PID 1 within the container.
Supervisor doesn't recognize environment variable in Nodejs
It seems that after typing supervisorctl reread you should also use supervisorctl update
supervisor - how to run multiple commands
Add a second section with a different task name. If two tasks have the same task name, the latter overwrites the former.

Erlang OTP supervisor gen_tcp - {error,eaddrinuse}
erlang,restart,otp,supervisor,gen-tcp
Is the process managing the gen_tcp socket a gen_server? If so, it will make your life easier. If it is a gen_server, add process_flag(trap_exit, true) to your init function. This makes it so that when your process "crashes", it calls the terminate/2 callback function prior to actually exiting the process....
Relationship of Akka SupervisorStrategies to children
java,exception,akka,supervisor

Can I import configuration files with supervisord?
environment-variables,supervisor
I didn't understand the part about wanting to keep conf.d public (why do that?), but aside from that, try using exec in the last line of the shell script: exec ~/src/handybot/bin/hubot -a xmpp Alternatively you can usually pass env vars like ABC=2 DEF=3 ~/src/handybot/bin/hubot -a xmpp I say "usually" only...

Schedule restart of Akka actor
scala,akka,delay,restart,supervisor
Delay on restart hasn't been implemented yet. Thread.sleep is out of the question performance wise. I see two choices : Have your main actor create the querying actor on a message. When it blows up because of a database outage, you can just stop the actor and re-schedule a message...

python,docker,environment-variables,supervisor
The variable is being passed to your container, but supervisor doesn't let use environment variables like this inside the configuration files.
