FLEXnet Licensing error:-15,570. System Error: 10035

After you clicked Perform Status Inquiry on the Server Status tab of LMTOOLS, the following error message was displayed.

lmgrd is not running: Cannot connect to license server system. The license server manager (lmgrd) has not been started yet, the wrong port@host or license file is being used, or the port or hostname in the license file has been changed.

Server name:   SERVERNAME
License path:  @SERVERNAME
FLEXnet Licensing error:-15,570.  System Error: 10035 "WinSock: Operation would block"


For further information, refer to the FLEXnet Licensing End User Guide, available at www.macrovision.com.

Client workstations were also unable to obtain a license.

The most common cause of this error is that the license server has not been started. To start the license server

1. In LMTOOLS, click the Start/Stop/Reread tab > Start Server. 
2. Return to the Server Status tab and click Perform Status Inquiry to verify that licenses are now available.

If you receive the error again, the configuration of the service could be incorrect. To check and, if necessary, correct the configuration 

1. On the Config Services tab, verify that all three paths are entered correctly and the 'Use Services' option is enabled. 
2. Correct any errors in the service configuration and click Save Service.
3. On the Start/Stop/Reread tab in LMTOOLS, click Start Server. 
4. Return to the Server Status tab and click Perform Status Inquiry to verify that licenses are now available.

Note: In some prior versions of FLEXlm it was not mandatory to specify a debug log file when configuring the service. This is now required for the successful operation of the Network License Manager.

If you continue to receive the same error when performing a Status Inquiry, there may be additional conflicts with the License Server that will require troubleshooting. Please contact Product Support for further assistance.
