** [tickets:#2712] msg: msgd crash during multiple node reboot**
**Status:** fixed
**Milestone:** 5.18.01
**Created:** Wed Nov 29, 2017 05:10 PM UTC by Alex Jones
**Last Updated:** Wed Nov 29, 2017 07:44 PM UTC
**Owner:** Alex Jones
If multiple nodes are rebooted at the same time and one of the nodes is the
active controller, msgd on the newly active controller can crash at AMF
assignment time.
There is a race condition in handling the CLM tracking notification. If the CLM
tracking callback is called more than once before the assignment has finished,
it is possible that "is_node_down" and "is_clm_down" can both be set to true.
In the AMF assignment code the node info is deleted for each node for which
these variables are set. But, if they are both set msgd crashes because of a
double delete.
