How to handle commands that hang on the remote end?

[Haani Niyaz]

We have a use case where we want to run a service tomcat stop command and if it hangs run a kill -9 <pid> command. I'm unaware of ways to handle this in Capistrano. 

Has anyone solved a similar issue..? if so, can you please share methods, thanks.

Versions:

• Ruby 2.1.1p76
• Capistrano 3.4.0

Hi Haani,

It's been 48 since your post, so I'm not sure if it's still relevant, however if tomcat is taking a long time to respond, there's not much Capistrano can do to handle that. 

The only real way is to make a command that backgrounds tomcat, collects it's PID and then signals it after a certain number of seconds, but it ends up being quite convoluted.

Bash's (assuming you're using the Bourne shell) FAQ #68 has a wealth of good information: http://mywiki.wooledge.org/BashFAQ/068

Thanks Lee. It does seem like something that should be handled by the tomcat init script so I've resorted to doing just that.
