I'm sitting JUST NOW in front of the LDAP Server and slapcat/slapadd
the database to reorganize ..
(database is almost 4 years old)
2 hours ago, booth servers crashed again ...
I can't belief, that 16G RAM not enough for 1500000 entires/objects ...
I need about 5G for set_cache_size (DB_CONFIG) and the other RAM (11G) is for
shared memory and the other caches (cachesize, dncachesize, idlcachesize).
How much need the three caches?
And if to less cache, the machines should run slower, but not run out of memory?

Softwareupdate is possible not before january 2013.
I was wrong with the version, we use 2.4.31
I'm looking to mdb since a few month, but is it usable for production?

Yes, not before january 2013 ...
Hope after reorganization, slapd runs more stable...
The only thing I can do for now.
