The subscription info process may hang when started during a NoMachine Service restart
When the 'nxserver --subscription' process, which is executed to check the current NoMachine subscription status, is started in parallel with, or shortly before, the 'nxserver --daemon' process started by the NoMachine Service, it may create the backend database.
When 'nxserver --daemon' later takes over this database, the subscription process does not behave as expected. Instead of reconnecting and retrying the command correctly, it may hang without returning any response.
This issue can also affect the installation process. At the end of the installation, the NoMachine Service is restarted, and then the installer executes the subscription check in order to print the proper license-related message. If the race condition occurs at this point, the installation process may hang or fail to complete correctly.
