Shell provisioning fails to exit #1553

Host OS: Win7 x64, Vagrant 1.1.5
Guest OS:

Using vagrant provision with shell provisioning, when I start a Java process with threads waiting for input (embedded Jetty server), the ssh session never closes.

The process is started like this: nohup java -cp my.jar my.MainClass arg1 arg2 &

It is then properly started in the background, and the next shell provisioned command executes. Yet, the vagrant provision command never returns.

Workaround: adding pkill ssh at the end of the shell provisioning command list and ignoring the stacktrace.

OK, I found a real solution.
It turns out whatever process that wants to stay running has to be properly daemonized. In order to do this one must detach stdin, stdout and stderr.

In my case this meant replacing

nohup &


nohup ./ 0<&- &>/dev/null &

Hope this helps someone else with a similar issue. Not sure if this could be simplified within Vagrant or not. (Autodisconnect of all standard in & outputs?)

Ah! Interesting. I'm not sure, but I'd love to know if this could be simplified in some way. Let me know if you (or anyone else) comes up with anything.

WOW, been wasting time with this since yesterday.
I was doing "nohup grunt server &" to start node.js through grunt
Replacing it with:
"nohup grunt server 0<&- &>/dev/null &" works perfectly
Thanks a lot.

This is great solution for nohup.

Thanks !
