The value of the hasSubordinate may be a symptom of the problem, but I 
don't think it's the cause, because its value is generated by asking the 
underlying BerkeleyDB dn2id database if the entry may have children.  
Your second interpretation of the X.500 wording is consistent with ours, 
i.e. hasSubordinate simply gives an indication whether an entry may or 
may not have subordinates at the time the request was generated.  That 
is, if you search an entry with hasSubordinates=FALSE with oneLevel 
scope, you may still find some subordinates and vice-versa.
