Ansys license manager error

    • cbur


      One of our customers has a problem with his floating license: every 30/40 minutes, he receives this message (see picture).
      He has to restart the License Manager service from the server and then it works again 30/40 minutes...
      Do you know where this can come from or have you already encountered a similar problem?
      For information, this problem appeared since the update to SpaceClaim 22.2

      I have retrieved the server and client logs if needed.

      Hello charlie

      Can you please let me know if you have updated the Ansys License manager as well?

      Was the Discovery and License manager done with Administrator rights?

      Let me also check with my team on this one.

        The license manager is in 22.1 and has been installed with administrator rights.

      Is the user on VPN? If the user has an idle spaceclaim while the VPN disconnects, licenses tend to get stuck. This is a flexera bug.. in this scenario, there are commands that can be run on the server side to release the stuck licenses without restarting the LM service. 

      When licenses get stuck due to abruptly changing networks (disconnect from VPN without properly exiting applications), bad network connectivity or abnormal PC crashes, it can be released using the below command from the server machine –


      "c:Program FilesANSYS IncShared FilesLicensingwinx64lmutil.exe" lmremove -c 1055@


      Now say for example, the spaceclaim increment is stuck “a_spaceclaim_dirmod” under the username charlie, the code will look something like this –


      "c:Program FilesANSYS IncShared FilesLicensingwinx64lmutil.exe" lmremove -c 1055@LIC_SERVER a_spaceclaim_dirmod charlie


      This will remove the stuck increment from your username without the need to restart the license server. If there are more than one increment stuck, then you can run the command multiple times to remove each stuck increment.
