Question

When we do system restart to load license module, following error occurs:

Licensing exception: Internal error: Error in FNE protocol: PosixMutexImpl::PosixMutexImpl: 
Could not verify lockfile directory access rights: No such file or directory.  

What is causing this error and how to avoid it?

Answer

The error "Could not verify lockfile directory access rights" indicates that your application do not have read/write access to /tmp directory to read the mutex of FNE application. Under the temp directory you will see files starting from "fne.*". These files are needed by FNE application to run.

If you think your application have read/write permission under /tmp then its possible that due to some other reason those files are somehow not being loaded. So to fix the issue, please delete those mutex files and restart the application. Doing so will create new mutex files.
