<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This may be a reference leak.
serializer_create will create an ao2 object with a reference count of 1.
When you ao2_link it into the serializers container, the reference count of the object goes to 2.
This means that the container does not hold the only reference to the object - so merely destroying the container will not destroy all objects in the container - it will actually orphan them.
On a successful ao2_link, you should drop the creation reference provided by serializer_create.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">While handling a registration request a race condition could occur if/when two+ clients registered at the same time. This happened when one request obtained a copy of the current contacts for an AOR and another request did the same before the first request updated. Thus the second would update and overwrite the first (or vice-versa depending on which actually updated first). In the case of it being the same contact two "add" events would be raised.
pjsip registration handling is now serialized to alleviate this issue.</pre>
