All these symptoms indicate a potential hotspot in this replica, which can be caused by one or likely multiple "hot" partitions. Finding out which particular partition(s) is responsible for this is tricky, but good candidates are the ones mentioned in the log warning.
Ideally you should fix your data model to avoid large partitions and hotspots, keep your partitions under 100MB. There are some bucketing techniques available to reduce partition sizes.
