There are cases where the main event handler in slapd may not take any 
action for a long time after an update. There's a change in HEAD to 
address this, but it wasn't rolled into 2.3. Since you say this is fully 
reproducible, please try compiling the syncprov.c from HEAD and see if 
the behavior changes. (The current HEAD syncprov.c is fully compatible 
with 2.3.)
