I have a simple upstart script that exec my daemon. When doing so, the correct pid is returned by upstart, but my daemon is not able to create the actual pid file.

    VM=$(cat /proc/meminfo | grep MemTotal | awk '{ print $2 }')
    ulimit -v $VM
    ulimit -c unlimited
    exec $DAEMON
end script

If I execute $DAEMON from the command line, then everything forks and the pid file is created as expected.


If you are using Ubuntu Raring/Saucy or Debian sid, you can easily install procenv to for full environmental details (as shown in the links above).
