I have setup a backup job and just noticed that for the last 4 days I've not have backups. When I look at the error details I get this:
Could not communicate with the VM agent for snapshot status. Snapshot VM sub task timed out.
When I login to the Ubuntu (14.04) machine and look at the processes I can see that waagent is running.

What can be wrong? I had this same problem about a month ago as well and I believe rebooting fixed it, but this is definitely not a permanent solution.
