Sometimes a license service will fails to release a license that is no longer. This is typically caused by inconsistencies or errors in the network communication. Devices on the network such as switches, routers, or firewalls can interfere with the communication between the STK client and the License Server.
The license manager initiates two TCP connections to check a license in or out:
- one which defaults to a range of TCP ports - 27000-27009,
- one on a random TCP port.
This dynamic/random second port can be blocked by routers, switches, or firewalls on the network between the license server and the client.
To reduce this problem, set the license manager to run on a static second port, and then open this port on all intervening network devices.
To do this add the desired port number to the DAEMON line of the Server License file. In the example below, the port added is
29000.
SERVER 10.1.2.82 00114365122a
DAEMON STKD port=29000
