I've been having some problems while importing some records into my ldap server and the server crashed with error (23 november)

Nov 23 12:06:55 berlinzoo slapd[29709]: ====> cache_add_entry( 184299 ): "cn=157041,ou=non iscritti,ou=<CUT> ": already in id cache Nov 23 12:06:55 berlinzoo slapd[29709]: cache_add_entry_lock failed Nov 23 12:06:55 berlinzoo slapd[29709]: cache_add_entry_lock failed Nov 23 12:09:09 berlinzoo slapd[29709]: ldbm: ==> page 3266: illegal page type or format Nov 23 12:09:09 berlinzoo slapd[29709]: ldbm: ==> PANIC: Invalid argument

When restarted, sometimes the server crashes so I've read some on google and decided to db_recover and then restart.

Yesterday (27 November) the openldap server worked "quite" well, but sometimes still crashes: Nov 27 08:09:53 berlinzoo slapd[8529]: ldbm: ==> page 3267: illegal page type or format Nov 27 08:09:53 berlinzoo slapd[8529]: ldbm: ==> PANIC: Invalid argument (infact it does not crash, my application just hangs and cannot use ldap server anymore)

I've noticed that my daily backup (I know, I'm stupid, I should have restored that backup the next day and not wait till now) since 24 is getting 2Gb (but just because it lock for max file size reached otherwise goes over 4Gb).

What I think is that there should be a kind of "circular" reference because normally the backup is 23Mb, not >4.5GB.

Anyone can suggest a correct procedure to get it stable without restoring the 23's backup file ?

Thank you very much Julien
