Facing error on concurrent execution of Camunda engine

Hi,
Getting the following error when we start two camunda engines.
We want have multiple parallel engines connected to a single Oracle 18C Database

ENGINE-03005 Execution of ‘DELETE EventSubscriptionEntity[46691c47-1597-11ea-8e3e-b00cd165f0cb]’ failed. Entity was updated by another transaction concurrently.

Seems like both the running instances are trying to access the table act_ru_event_subscr at the same time.

Tried disabling the jdbcBatchProcessing but still giving the same error
