RLNKCTLRNDWNFL, Relinkctl file for $ZROUTINES directory dddd failed to rundown as it is open by nnnn process(es)
MUPIP Error: MUPIP RUNDOWN -RELINKCTL attempted to rundown the Relinkctl file for directory dddd, but did not because there were nnnn processes still using it.
Action: This may be expected, particularly if the command has no directory argument specified. Target MUPIP RUNDOWN -RELINKCTL to directories that are not currently in use, which under some circumstances can require stopping processes.
