3.3.2.1.2 Association Active Context Handle Count
Association Active Context Handle Count: The client version of the Association ADM element, as described in section 3.3.1.1.1, includes a count of active context handles, stored in a 32-bit unsigned integer. When a new association is created, the count is zero. The Association Active Context Handle Count is incremented when context handles are created for an association according to the mechanisms described in [C706]. Likewise, the Association Active Context Handle Count is decremented when context handles are released. The client SHOULD not allow the count of context handles to overflow the data type, although the chance of doing so without exceeding the server's resource limits is very minimal.
