Oren Cohen commented on DIRSERVER-2192:
---------------------------------------

Hi Emmanuel,

I'm running M21 on Windows, and got corruption with error: ERR_562 Offset too large for record
header
I cannot install M23 using the installer, so I took the service JAR of M23, and replaced it
in the ApacheDS lib folder.
I ran the apacheds.bat with repair option and got this log:

Service started.
Repairing the database.
Repairing partition dir <My server folder>\ApacheDS\Server\bin\..\instances\default\partitions
Re-building indices...

I then got ~2000 messages like this:
Read entry cn=case_111352296_read with ID 002c5d0c-e590-4775-909f-b0e5aad7ea1e and parent
ID 82dfe019-c369-4ad1-8df4-e33f3c904836

Then got:
Updating the RDN index counters...
Total entries present in the partition 2096
Repair complete
Database repaired.

(I didn't get a prompt back)
When I open Apache Studio I see that all the tree under RootDSE has disappeared. I have no
entries there.

1) What happend ?
2) How can I fix it ? I tried to rerun the same command but got the same results and log.
3) Can you tell what's is the scenario of the corruption bug ? If the repair can damage my
Ldap, I prefer avoiding the corruption as much as possible.
4) What should I do in order to avoid the corruption ? Does it happen when ApacheDS has to
many users or groups ? Is there a limitation (I have ~2000 I guess).

Thanks a lot !
Oren
