Just FYI, note that there was a similair issue fixed in event service long back.

** [tickets:#1396] log: issue with priority of messages adding to mailbox in
the server**
**Status:** assigned
**Milestone:** 5.0.FC
**Created:** Mon Jun 29, 2015 09:14 AM UTC by Vu Minh Nguyen
**Last Updated:** Mon Nov 30, 2015 08:12 AM UTC
**Owner:** Vu Minh Nguyen
If there are several initialize and finalize done in a row in the same process,
there is possibility getting SA_AIS_ERR_BAD_HANDLE.
[Test sequence]
1. saLogInitialize()
2. saLogFinalize()
3. saLogInitialize()
4. saLogFinalize()
--> get error SA_AIS_ERR_BAD_HANDLE
Here is the problem:
====================
The finalize request will delete the requested client and the agent will wait
for the answer (ack). If the last client initialized by this process is
finalized the agent will free the resources used by the agent which means that
the mds also is finalized which results in an agent down event on the server
side.
The agent down message to the event handler is placed in the mailbox queue with
the lowest priority.
In this test sequence the next thing that happens is that the agent is started
again and a new initiate request is sent. When this request is received on the
server the initialize message to the event handler is placed in the queue with
the highest priority.
What happen in this case is that the event handler has not yet fetched the
agent down message when the initiate message is queued which means that the
order of handling the messages will be initialize (highest priority) and then
agent down (lowest priority).
- The initialize will create a client
- The agent down will remove all clients for the agent process including the
just initialized
- The agent sends a finalize and gets BAD_HANDLE as a reply in the ack from the
server since the client is already deleted.
