How to release a license stuck in 'checkout' state

The guidelines below shows how to release a license that has been stuck in "Check Out" due to a network connection, application or other issues. This requires admin or root access on the license server running the Ansys License Manager. Do the following after 15 minutes that the client machine lost connection with the license server.

Checking the license feature

• Log into the license server hosting the Ansys license manager.
• Open a terminal or command prompt.
• Run the following to check the license feature that is "stuck in check out".
  
  • Windows:

    "C:\Program Files\ANSYS Inc\Shared Files\licensing\winx64\lmutil" lmstat -c 1055@localhost -a 

  • Linux:

    /ansys_inc/shared_files/licensing/linx64/lmutil lmstat -c 1055@localhost -a

• If you changed the license manager port (1055) use that port in the command below.
• Take note of the license feature, user, hostname, and display information.

Releasing the license feature

• Remove the stuck license using the feature, user, hostname, and display information as shown in the output from above. Default install path shown. 
  • Windows:

    "C:\Program Files\ANSYS Inc\Shared Files\licensing\winx64\lmutil" lmremove -c 1055@localhost [feature] [user] [hostname] [display]

  • Linux:

    /ansys_inc/shared_files/licensing/linx64/lmutil lmremove -c 1055@localhost [feature] [user] [hostname] [display]

• From the sample image, we remove the lum_fdtd_gui, license feature, in-use by user: lyapon host: vnrlyap on display: vnrlyap :

  "C:\Program Files\ANSYS Inc\Shared Files\licensing\winx64\lmutil" lmremove -c 1055@localhost lum_fdtd_gui lyap vnrlyap vnrlyap

If the license cannot be released using the above process

• Wait for the license manager to release the license after the default "idle timeout" of 2 hours or, 
• Stop / Start the Ansys license manager (Windows / Linux)
