There is a case that after AMFD send reboot order due to “out of sync window”.
AMFD receive CLM track callback but node is not member yet and delete node.
Later AMFND MDS down will not reset msg_id counter since it cannot find node.
When node reboot up, AMFD continue use current msg_id counter send to AMFND
cause messasge ID mismatch in AMFND then AMFND order reboot itself node.
