7.6.6 Event log output at each stage in the life cycle
An event log is output at each stage in the life cycle of the Explicit memory block. The event log is output when an event
leading to output occurs.
The following table describes the mapping of each stage in the life cycle and the timing of an event log output. An event
leading to log output varies according to the set log output level.

In addition to the preceding event log data, event log data is output independently of the stage in the life cycle when GC
occurs.
