Language was previously proposed, but not accepted as it was incomplete or ambiguous. There is a desire to define a method for a NF to denote that an overflow of buffered events occurred, and some messages may have been lost.

The following is needed:

• How should this condition be reported (fault, etc.)
• What content should be included in the reported event
• Where should the event be placed in the buffer for eventual delivery
• When should it be raised, cleared, and re-raised

Previously suggested language:

Overflow
********

If the internal event source event buffer or local storage should overflow, then
the event source should send a Fault event, and should discard events in a
first-in, first-out (FIFO) manner (i.e., discard oldest events first).
