after the August2011 maintenance patch sysvolsync leaks processes every
30 min. So if you have more than one DC, remember to kill all the
"/usr/bin/ssh -q -f ..." on your DSfW-PDC every few days until an
updated sysvolsync is out, otherwise the PDC will become very unhappy I
guess ;-).
I've opened SR#10720855051 for this problem.
