hello,
I have some problems with my ldap server. it worked perfectly until monday, march 30 : on every night, I used to extract all entries from the server, making a diff with some ldif file(s) and ldapmodify with the "diff ldif file".
there was about 15,000 to 40,000 entries modified each night, and ldapmodify was running about 20 to 40 minutes (~1,000 entries per minute).
on last monday, the extraction of ldap had some trouble, the extraction request never ended, and that made the server inaccessible; we had to restart it. since march 30, the update process (ldapmodify) is incredibly slow, it takes about several hours (~60 entries per minute), but the extraction request is "normal" again (about 2 seconds).
we tried to restart from scratch (delete db, re-install openldap (and update) and start the process again, it is still slower than before (~400 entries per minute). we cannot figure out why it became so slow, so we are interested in any advice... we had openldap 2.3.27-8.el5_2.4 installed and tried with the update: openldap 2.3.43-3.el5 (both CentOS packages).
