The license manager (lmgrd) is running, but no Mentor Graphics licenses are available because the mgcld (vendor daemon) is not running. The PADS products may fail to launch until both the lmgrd and mgcld are up and available.
Check with your administrator to make sure the license manager has been configured for Mentor Graphics (mgcld) licensing.
Check that no firewall is blocking the communication. If there is a firewall between the license server and client machines, you must open the firewall to the lmgrd port (fourth field on the SERVER line in the license field, default value is 1717).
The port for the mgcld (vendor daemon) must also be opened. By default the mgcld port number is dynamic. To assign a static mgcld port refer to the Licensing Mentor Graphics Software manual, and specifically the Firewalls section.
