Why do I receive an error about redundant server communication when starting the license manager using the lmstart command?

Solution:

On Linux, UNIX and Mac systems this error can be resolved by following the steps below:

1. In a terminal window, browse to your MATLAB/etc/ folder.
2. type: ./lmdown
3. type: sudo rm /var/tmp/lm* (enter your Mac password when prompted)
4. type: sudo rm /var/tmp/lock*
5. type: ./lmstart (check for error messages)
6. If there are no errors displayed, try to run MATLAB again
