Ok, I can downgrade to the versions we had before, but we still need the 
problem solved somehow. If the LDAP directory that we base the whole 
server-config on is not reliable, it doesn't really matter if it 
performs well or not.

Do you have suggestions for slapd/bdb config-parameters according to the 
following priorities:

1) Reliability
2) Read performance
3) Write performance

Write performace can suffer badly to improve the two other priorities. 
So any kind of write caching etc. can be disabled, no problem.
