Azure Web Job Not Triggering When Messages are added to the queue

I am attempting to diagnose the root cause of unwanted behavior exhibited by an Azure Web Job I am running.

The Facts:

I have a an Azure Web Job that works most of the time, however every couple of days it just stops processing messages.

CPU and Memory seem fine: enter image description here

You can see the last successful run was several hours ago: enter image description here

There are several hundred messages still in the queue:

Having confirmed nothing has been changed as far as configuration or executable in the last 24 hours, what could be causing this behavior?
