Hi All, I'm migrating our ldap service from Sun One to OpenLDAP. In the process I have stumbled upon this issue a couple times. 1. Initialize Master 2. Connect syncrepl slaves 3. Wait a week 4. Replication stops working with `null_callback : error code 0x12` in slave logs and lots of ugly output in the master logs 5. Reinitialize master, GOTO 2 We started with slapd 2.4.7-6ubuntu3, then upgraded to 2.4.9-0ubuntu0.8.04.2 to see if it would help the issue, but it has returned. I spoke with Howard at LISA'08, and he mentioned this may be resolved in a newer release. Has anyone else seen an issue like this, and is it worth my time to backport a newer version to Ubuntu Hardy (our server platform of choice)?
