** [tickets:#1728] amfnd: message ID mismatch causing node reboot**
**Status:** fixed
**Milestone:** 5.0.RC1
**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.
