Hi David, For the moment we should assume that the Docker image is not the cause of the problem, since that should have no effect on the ESM. The Task Watchdog indicates that the task called “Cyclic100” is taking longer than 100ms to execute. Without knowing what that task is executing, I am afraid that it is impossible for us to say what is causing the task to execute for longer than 100 ms. ~ Martin.
