Hi,
I've been having issues with syncrepl in openldap. This is plain syncrepl. I'm not using delta-syncrepl as I run with mirror mode on.
I've noticed that when there are a large number of writes on the writemaster (Typically around 10 per second) the data on the readslave goes out of sync with the master, typically having entries which have been deleted on the master. The contextCSNs on both the readslaves and writemaster match eventually, but the data doesn't. I'm running the readslave in refreshOnly mode with an interval of 1 minute. I'm using a reasonably large DB of size ~ 2 GB. I turned on the sync logs and found lots of entries with "nonpresent_callback" and "syncrepl_del_nonpresent".
Tested this and found it occurring in both 2.4.29 and 2.4.33 (Latest as of this time), and with BDB 4.2.36 as the backend.
I was wondering if anyone has faced similar issues before, and if there exists a solution to this problem. I will send any relevant configuration and log snippets as needed.
Thanks
