If you encounter this error when starting Moab, make sure your Moab license file is named moab.lic and is located in the /opt/moab/etc/ directory.

Also make sure the license is not expired. The expiration date is listed in the license file. For example:

# cat /opt/moab/etc/moab.lic
...
# Expires after Tue Dec 31 10:43:46 2013
...
