The BDB patch affects a locking issue, it usually results in making the 
server hang.

I have no idea what is causing your crashes. Perhaps you should use a 
debugger and get a trace from one of the crashes to see where it 
occurred. First, I would obtain the OpenLDAP 2.2.12 release which has 
just been made available. There's no point in chasing down bugs in 
2.2.11 that might already be fixed.
