I do have sync logging enabled. This is the last record in the log file, and after that, nothing. It isn't attempting to get changes.
Log on the replica: Dec 12 08:59:30 aaa-prod-gcp-9 slapd[4165]: slap_queue_csn: queueing 0x7f67101bc860 20241212135921.652395Z#000000#000#000000 Dec 12 08:59:30 aaa-prod-gcp-9 slapd[4165]: slap_graduate_commit_csn: removing 0x7f67101bc860 20241212135921.652395Z#000000#000#000000 Dec 12 08:59:30 aaa-prod-gcp-9 slapd[4165]: slap_queue_csn: queueing 0x7f67102311b0 20241212135921.652395Z#000000#000#000000 Dec 12 08:59:30 aaa-prod-gcp-9 slapd[4165]: slap_graduate_commit_csn: removing 0x7f67102311b0 2*0241212135921.652395Z#000000#000#000000*

There is nothing in the log on the master or the replica after this entry.

Hi,
We have a single master with multiple replicas. Our backend is mdb, and we are on the latest version, 2.6.9. The replication type is refreshAndPersist. Here is the relevant configuration.
syncrepl rid=141 provider=ldaps://ldap-master.georgetown.edu:636/ type=refreshAndPersist
.. .. keepalive=300:5:5 retry="5 5 300 +"This is now happening at regular intervals. When a consumer replication gets stuck, only a service restart seems to restart replication.
Need more information on what you mean by "getting stuck". Is it actually attemping to get changes? Do you have sync logging enabled? If so, you could see if that particular consumer is having an issue during replication and returning a non-zero result code as to why it's unable to proceed. Or is it not establishing a replication connection at all? etc.
