Couchbase Lite replicator errors when offline

Mobile Couchbase Lite

Couchbase Lite 1.4.0 replicator gives errors when offline. When I switch off WIFI to simulate loosing internet connection, I expect the replicator pauses and resumes replication when the internet connection is up again.
I use continuous replication.

However I see in the console a lot of exceptions thrown by the ChangeTracker:

Nov 22, 2017 10:02:59 PM com.couchbase.lite.util.SystemLogger w
WARNING: ChangeTracker: ChangeTracker{http://xxxxxxxxxxxxx:4984/sync_gateway/, LongPoll, @2aca7530}: Exception in change tracker
java.net.UnknownHostException: xxxxxxxxxxxxxx
(where xxxxxxxxxx is the host that runs CouchBase Sync_Gateway and CouchBase Server)

Is this normal behaviour? Should I simply ignore the exceptions?
