I have personally only ever needed a shared memory key on one of a group of ldap servers. But i noticed that the bdb logs are not written to disk when shared memory is configured, is this a good or bad thing ? If the power is lost, without bdb logs, could this leave bdb in an unrecoverable state ? Cheers Brett
