The 800004FF task error indicates some task is in an infinite loop and has not given up time for lower priority tasks to run for a lengthy period of time.

Recently a customer had this task error after an XL firmware upgrade and enabling Eclipse. The controller’s screen was constantly refreshing. When Eclipse downloads orders and other things, a screen update is initiated. The theory is that the customer had so much data to download that it kept the PEG graphics task (responsible for screen updates) too busy and it did not have time to rest and give up CPU time.

The software has now been modified to force the PEG graphics task to rest at least once per second. Assuming the theory is correct, this should eliminate the task error the customer was experiencing with Eclipse after an XL update or after a memory clear.
