One  customer reported a very interesting issue with graceful splunk restart.

Event missing during a graceful restart/rolling restart(splunk stop gracefully finished). useACK=true is an option but that ideally must be applied if splunk stop timed-out. This has been an issue for so many years.

This is important where config changes are pushed frequently, thus triggering frequent indexer/HF/IF restart.

The issue is fixed by 9.1.4/9.2.1
