Events are not being stored in Database (AxonFramewrok + Kafka)

My projects includes axon-framework with version 3.4 and kafka-distributor as event processor. At first when we deploy our app to producation, there was no problem with axon-framework. Now, our app has a large amount of data, databasize size is extremely big(more than 80GB). Recently, A problem occured, the problem is that events are fired from aggregates, both @EventHandler & @SagaEventHandler handles the event and process bussiness logic, but those events are not stored in domain_event_entry and saga is also not storing those events as well as global variables in it and this is causing data consistency.
Any help would be appreciated, Pleaseā€¦
