Some GNU Radio applications are written to try to set the process
scheduling priority to realtime in order to obtain the best possible
performance.  However, unless your system is specifically configured
to allow your userid to have this privilege, it will fail with the
above error message.

This is not in itself a problem unless your application needs the
extra performance.  You will need to consult the documentation for
your specific OS to determine how to enable this, or run the
application as the root user.
