Rather than using returns to get around the problem, wouldn't it make more 
sense to check for a PID using ps?  It's entirely possible to have a 
process that's running with no pidfile.

Something like this would work (I've used it before):

if [ -z "$rc_pid" ]; then
  blah
else
  test_pid=`ps -auxw | grep "${name}" | awk '{print $2}'`
  if [ "$test_pid" -gt 0 ]; then
    kill -s HUP "$test_pid"
  else
    echo "${name} not running?"
  fi
fi
