No. It sounds like you don't have a checkpoint directive set for your
database. You should fix that.
You are right, now that I added
checkpoint 200 240
in the slapd.conf, bdb files are bigger !
in fact my old repicas in 2.3 had that directive in global configuration
whereas apparently in 2.4 that directive must be in a database
definition, that's probably why I missed that one during the migration
process .
thanks .
