As you have added the save idle record to the lima_sched_handle_error_task which is just the if {} part of the following code, so no need to call it twice for error tasks. BTW. lima_sched_handle_error_task is also used for timeout tasks, so add idle record in it is fine.
oh, that is a good catch - thank you! I will fix that in the next version
