Simple automation working but generating log errors

Configuration
1

I have a set of very simple automations that is generation more errors that I can believe. The job is to generate a simple html command send. It works often, but fails often as well. The errors seemed to start with either 64.3 or 65.0, not sure which. I am currently running on 65.2.

I have imaged 3 different cards and the issue persists. 2 of the cards were new Sandisk Ultra 16gb cards. I have a couple more cards on the way and a much more modern writer. Running on an RPi 2 with no lag or performance issues apparent.

These update 1 ESPEasy device that displays the data and passes it on to others via ESPEasy global sync. I have staggered the trigger times thinking that maybe it was just to much i/o in one burst. This did not change the behavior at all. They all execute perfectly on the command line. I am seeing a second error in conjunction with these errors, see below.
