Travis builds hang at the end

[phoe]

Hey! I have an intermittent issue where my Travis jobs hang and time out.

One example is https://travis-ci.com/phoe-trash/ccl/jobs/250005919 where the job hangs, but I cannot rule out that the currently executing process from the job script is to blame.

A better example of that is https://travis-ci.com/phoe-trash/ccl/jobs/250005918 where the job is successful goes all the way to Done. Your build exited with 0., but then it hangs and times out.

How should I start debugging this? Is it possible for Travis’s shell to at least print what process occupied the shell, or to send a SIGINT to the busy process in question, wait another few seconds to let it produce some debug output, and only then terminate the job?

Job still running after "Done. Your build exited with 0."

Accordng to Windows build hangs after Done exit 0, this happens if some background processes are still running. To compare process lists before and after, e.g. run ps -W | sort at appropriate moments, then diff the outputs. To get the command line of the culprit, read /proc/<pid>/cmdline as per https://superuser.com/questions/1247844/full-command-text-with-ps-on-cygwin.

@native-api Thanks for the reply! This should help me debug.
