LDBM is a problematic backend that is being removed from OpenLDAP with the 
2.4 release.  I think it would be well worth your time to use BDB.  I will 
note that OpenLDAP 2.3 support auto recover on reboot, so assuming you have 
properly configured OpenLDAP (checkpointing, etc), you can reboot without 
too much issue.  Of course, you should always shut down slapd cleanly 
before rebooting so that anything in the cache that hasn't been 
checkpointed yet is written to disk...

I will note, however, that the people responsible for packaging OpenLDAP 
for your distribution appear to be woefully behind in their duties, as the 
current OpenLDAP release is 2.3.21 (and 2.3.22 will be out in a few days). 
I would advise using the latest release of OpenLDAP, as hundreds of bugs, 
some critical, have been fixed since 2.3.11 was released.
