Corrupt DB after Reboot

[Matthias Spork <hallo@matthiasspork.de>]

Hello,

each time I reboot my Server, OpenLDAP goes corrupt. I had to slapadd a 
backup from an other server. This behavior is on all my SLES9 Server, 
which runs with same configuration and OpenLDAP-versions.

Could you give me a hint, where I can more analyse my problem?


I played with the DB_CONFIG. I changed the file an rebuilded the db 
(slapcat & slapadd). After first reboot it seemed to work. Am I on the 
right way?

Old DB_CONFIG:
set_cachesize 0 15000000 1
set_lg_regionmax 262144
set_lg_bsize 2097152
set_flags DB_LOG_AUTOREMOVE

New DB_CONFIG:
set_cachesize   0       26214400        0
set_lg_max      10485760
set_lg_bsize    2097152
set_lg_dir      /var/lib/ldap/transactionlog
set_tmp_dir     /tmp

Kind regards
Matthias
