The error message that you've seen in your log file indicates that when the
RRD MA service starts its LS registration attempt it cannot find the RRD
description file, which contains the info which should be registered. I don't
know why, sorry. Could anybody else provide some clues what might be wrong?

The LS registration attempt is triggered by the first request sent to the RRD
MA service (possibly by perfsonarUI). It is only at this point that the RRD MA
gets fully initialized and starts its periodic LS registrations.

I've checked that perfsonarUI receives an empty response from the service,
probably for the same reason as the LS registration problem.

Best regards,
Vedrin
