Understanding Heroku server status 143

Question

I'm wondering about Heroku server status and can't find any documentation about this topic.

Example:

Process exited with status 143 

Can anyone explain this example? And where would I find resources for future reference?

Answer 1

Exit code 143 means that your process was terminated by a SIGTERM. This is generally sent when you do any commands that require your dynos to restart (config:set, restart, scale down...).
