Symptoms

When starting the license server the following error may be produced.

18:58:06 (flexera) Vendor daemon can't talk to lmgrd (Cannot read data from license server system. (-16,287))

Cause

This can be caused by using ports in the license file that are already in use.

The license server (lmgrd/lmadmin) and the vendor daemon both use ports and can be specified in the license file.

For example:

SERVER this_host ANY 27005
VENDOR flexera PORT=27010
USE_SERVER
FEATURE...

Where 27005 in the license server port and 27010 is the vendor daemon port.

Resolution

Change the port numbers in the license file and restart the license server.
