In the script:
/usr/local/penrose-server-pro-2.0b5/bin/penrose-server.sh

There is a section that looks like this:

PENROSE_PID="$PENROSE_HOME/logs/penrose.pid"


if [ "$1" = "start" ] ; then

 if [ -f "$PENROSE_PID" ] ; then
   echo Penrose Server is running
   exit 1


The problem is that if the machine is rebooted, the $PENROSE_PID
file might still exist from the time the machine was last up
and running.  This was preventing the script from starting up
penrose properly (and this in fact is what was happening)

use running() that can be called to validate the pid.

running()
{
    [ -f $1 ] || return 1
    PID=$(cat $1)
    ps -p $PID >/dev/null 2>/dev/null || return 1
    return 0
}

it uses ps to validate the pid

Using PS() to validate the process name. If PS(dangling_pid) != name of the actual process then we will delete the dangling PID and start the server.
