Hi Quanah,

Understood. Unfortunately, we are experiencing the issue. Here is my configuration.

On Master:

database mdb

suffix "dc=georgetown,dc=edu"

dbnosync FALSE
checkpoint 128 5
maxsize 108993459200

# Replication
overlay syncprov
syncprov-checkpoint 10 5
syncprov-sessionlog 100

On the Replica:

syncrepl rid=132
provider=ldaps://aaa-master-1.uis.georgetown.edu:636/
type=refreshAndPersist

keepalive=300:5:5
retry="5 5 300 +"

How do we go about fixing this?

Thanks,

Suresh

I've been running OpenLDAP in AWS on EC2 instances for the last 3 years at
two different companies, and have never encountered this behavior.
