The following errata report has been held for document update 
for RFC6733, "Diameter Base Protocol".

Status: Held for Document Update
Type: Technical

Section: 8.16

Original Text
-------------
By including Origin-State-Id in a message, it allows other Diameter
entities to infer that sessions associated with a lower Origin-State-Id 
are no longer active.
If an access device does not intend for such inferences to be made, it 
MUST either not include Origin-State-Id in any message or set its value 
to 0.

Corrected Text
--------------
By including Origin-State-Id in a message, it allows other Diameter
entities to infer that sessions associated with a lower Origin-State-Id 
are no longer active.
If an access device does not intend for such inferences to be made, it 
MUST either not include Origin-State-Id in any message or set its value 
to 0. 
As a special case when the value of Origin-State-Id changes from 
4294967295 to 0, then also the access device  clear all the sessions.

Notes
-----
Origin-State-Id is defined as Unsigned32 in RFC 6733, Section 8.16. So the maximum 
value it can have is 4294967295. If the system restarts many times and the value of
Origin-State-Id reaches the value which is same as its maximum value 4294967295. 
Then what will happen for the next restart. At the next restart the value of Origin-State-Id 
will be 0 if we try to increase the value of Origin-State-Id.
It is not defined in the RFC 6733, that how the system should behave after 4294967295-th 
restart with respect to Origin-State-Id.

Generally when the peer receives an increased value of Origin-State-Id, then it clear all sessions.
If the value of Origin-State-Id reaches its maximum i.e., 4294967295, then after another restart 
its value will be 0. For a special case for transition of value of Origin-State-Id from 
4294967295 to 0, the peer should clear its session.
