Hi,all.

well some months,but now,something had happened.slapd couldn't start.
   When I typed 'slapd -d 5',it showed:

slapd stopped.

    Is there something wrong with the DB? Can anyone tell me how to
fix it and let slapd start?
    thank you.

Try running db_recover, but this looks somewhat like you have different BDB libraries than before.

It looks more like somebody manually truncated the log files. A regular db_recover won't help here, maybe a catastrophic recovery will. You might want to ask in the comp.databases.berkeley-db newsgroup about how to recover when your log files have been manually erased. And you definitely need to read the SleepyCat documentation, and make sure nobody makes that same mistake again.
