A few of our iOS devices seem to have started doing a full replication of all the data. Using Couchbase Lite 2.8.2 and Sync Gateway 2.8.2. Couchbase Server 6.5.0 all CE
In the Sync Gateway logs I can see that the sequence number for one of the devices was 4824929 yet the total number of sequences was 155680515.
This device is turned on every day and was up to date, so I would have expected it to be higher (there weren’t 100000000 changes in a day).
The only thing that I can think of that has caused this, is that we started up some new devices that had no data on, so these are doing a full sync. Is there a reason why if new devices start syncing, it would cause every other device to do a full sync, despite already being roughly up to date?
Another thing to note is that the replication.status.progress.completed/replication.status.progress.total numbers don’t change whilst it is going over the changes the device already has and the addDocumentReplicationListener doesn’t pass any documents, which makes sense I guess.
Might be related to other issues I have raised
