You need to upgrade, 2.4.44 is about 4.5 years old and numerous significant
bugs have been fixed with replication since then. It's absolutely unsafe
to use 2.4.44 for MPR (also, I'm going to assume you're correctly using
delta-syncrepl). 2.4.51 is the current release, change log is here:

Thank you for the quick reply and reference.

No, using syncrepl. Should we move to delta-syncrepl?

I can agree with that. We are using the distro provided openldap package and it’s pretty key to our infrastructure. So having it up to date is good. We have already tested this before and the migration to symas openldap is very easy! Thank you for that.

At least with my previous questions, are they any concerns in 2.4.51?
