Hi Jimmy,   Are you deploying with Capistrano and you originally started
Unicorn in a working_directory that no longer exists on the filesystem?

Under Linux, you can check the working directory of any process
with `ls -l /proc/$PID/cwd`

That's the only thing I can think of at the moment.

In your other email:

Shouldn't be possible unless your OS is broken.  A more likely
explanation is that Unicorn process is pinned to the working
directory of an old deploy.
