For the past day or so, freeswitch has been crashing with a malloc error.  We have been running with this configuration for over a month without errors.  Now we are seeing these errors. We have 4 servers and all of them are experiencing this.   Has anyone seen this before?

We are running 1.7.0.599 on Centos 7.2.1511.
