Just a stab in the dark, is the command expecting standard in/out to be
present/correct? There's a bunch of different ways to spawn subprocesses in
Python to better emulate what your shell already does in terms of setting up
pipes.
When you're running the command outside of Jenkins, are you still running it
with the Jenkins user on the machine? If not, it may be relying on some state
in $HOME or elsewhere that the command doesn't have when executing on the build
node itself.
Just a couple random thoughts, good luck :)
