Summary

This article will explain how to overcome the following error:

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

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))
18:58:06 (flexera) EXITING DUE TO SIGNAL 28 Exit reason 5
18:58:08 (lmgrd) flexera exited with status 28 (Communications error)
18:58:08 (lmgrd) Since this is an unknown status, license server

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 which can be specified in the license file. For example:

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

... where 27005 is 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.
