attempts to keep all replicas of a directory consistent. High convergence means 
CDS makes one attempt to immediately propagate an update to all replicas. If

a skulk 
occurs at least once every 12 hours on a directory with high convergence. High 
convergence is expensive, so constant use of it is not advisable. To control 
convergence, you modify a directory's
.B "CDS_Convergence"
attribute.
