Symptoms

It had been noted that due to some OS dependencies, post a reboot the FNLS (Flexnet Licensing Service) is unable to start automatically and which leads to a failure of multiple kinds on virtualization platform based licensing.

Diagnosis

/var/run/FNP directory is getting deleted after restarting the machine and FNPLicensingService is not able to create the /var/run/FNP/FNPLicensingService64.pid file.
