Error: -96 Server machine is down or not responding

Problem:

The lmgrd process is not responding on the default (27000) or custom port given in the application.

Cause:

Firewall

The firewall may be blocking the port used by lmgrd. While lmgrd itself will by default listen on IPv6 at port 27000, it is possible to use a custom port by editing the license file. This is covered in the next section (See Ports).

Multi license system

If more than one company’s license server is being loaded on the machine, there is likely a port conflict, this is most obvious within the license log file. The license log file will say that either the port number is in use, or that there is already an instance of the license server running. Then looking in the list of running processes thinkbox cannot be found in the list of running processes.

As Thinkbox’s lmgrd is using IPv6, it is also entirely possible that there is no conflict, but that requests for licenses are being sent to the IPv4 port instead.

LMGRD is not running

The license server application lmgrd isn’t running for one of many reasons.

The hostname may not be resolvable

If the client machine is using a host name instead of an IP address to refer to the license server, it’s possible that the client machine trying to connect is unable to resolve the name with the associated IP address.

Solution:

Firewall

Solution: To verify that the firewall is in fact the cause, temporarily disable it if it is safe to do so. If disabling the firewall allows licenses to be checked out, you will need to allow lmgrd and likely thinkbox to pass through. It should be possible on OS X and Windows to either; create program-based exceptions to the firewall allowing any ports from lmgrd, regardless of number, or set custom ports for both the license server. On Linux, you must use the port number.

Refer to our page on disabling or configuring your firewall for instructions on this. As well, for more information on setting a specific port see Setting License Server Ports.

Multi license system

Solution: You can resolve this by adding a specific port number at the end of the SERVER line in your Thinkbox license file. Refer to our Ports page on this topic for more.

LMGRD is not running

Solution: In the list of running programs for your operating system, ensure that you are viewing all processes for all users and verify that the lmgrd license server is running. If not, you will need to refer to the license server log file which should be named ‘Thinkbox.log’ in the root of the license server installation directory.

If the problem is not immediately obvious, don’t hesitate to contact Thinkbox Support.

The hostname may not be resolvable

A simple test would be to try to run the command ‘ping hostname’ where hostname is the one you entered for the server name. If no answer returns, this is likely the problem. To close the command on Linux and OS X, hold the control (‘ctrl’) key, and press the ‘c’ key.

Solution: If the ping command was unsuccessful and you know the IP address of the license server, you may use that on the client instead in place of the host name. If you have a systems administrator, it would be best to bring up this error with them.
