[389-users] 389 crash libdb: PANIC: fatal region error detected

Fri Aug 2 07:39:48 UTC 2013

If the database panics, it has detected a state of inconsistency it 
cannot resolve and sets a panic flag to the database environment to 
prevents its use. Just restarting the ds will detect the flag and abort.
You can try to remove the __db.00* files and then start DS again, if 
this fails you need to rebuild the database either by a bak backup or 
ldif import.

Why it did panic, I think we can no longer find out.
