SSFILCLNUPFAIL, Error while unlinking snapshot file -- xxxx
MUPIP Error: An attempt to terminate snapshot file maintenance by GT.M updater processes encountered a problem.
Action: Try a MUPIP RUNDOWN. If that has a similar problem, it may be prudent to shut down all access to the database in question in order to stop the burden of maintaining the snapshot file and to ensure it doesn't unnecessarily consume more space.
