I'll give that a try. I had perhaps been taking the advice given in the 
slapd-mdb man page too seriously:"Note: It is important to set this to as large 
a value as possible, (relative to anticipated growth of the actual              
data over time) since growing the size later may not be practical when the 
system is under heavy load."
