Is azure patch management shutting down my machine?

[lovettchris]

Describe the bug
My VM was running for months up until a few days ago. Now something keeps shutting it down and the last thing in the log before the shutdown is always Azure Patch Management?

To Reproduce
Steps to reproduce the behavior:

1. create Ubuntu VM
2. start the machine
3. run something on the machine that pings an Azure table every 60 seconds
4. Make sure it stays running forever

Expected behavior
The machine needs to run 24x7

Screenshots
This is what I see in the log
