** [tickets:#1728] amfnd: message ID mismatch causing node reboot**

**Status:** invalid
**Milestone:** 5.1.FC
**Created:** Wed Apr 06, 2016 08:39 AM UTC by Gary Lee

"Message ID mismatch, rec %u, expected %u" can sometimes be seen on a node.

This seems to be caused by the addition of the IMM reader thread.

In various message handlers, rcv_msg_id is recorded:

        avnd_msgid_assert(info->msg_id);
        cb->rcv_msg_id = info->msg_id;
        
But now we potentially have the main thread and IMM reader thread updating this 
concurrently.

The update of rcv_msg_id should possibly be done in a single thread. Eg. in 
avnd_mds_rcv() when a message is received from AMFD.
