The test isn't waiting long enough for the output buffer to overrun. This problem is happening because an error from the previous test is bleeding into the current test's logs. The simplest fix would be to split these tests.

Notice from the master test logs, the client which reached COB limit is client 11 which was created in Test dual-channel-replication primary gets cob overrun before established psync.
