Research direction
Start at gems/resque-scheduler-4.9.0/lib/resque/scheduler.rb:253, where the reported error occurs during enqueue_items_in_batch_for_timestamp. Reproduce the failure with release 4.9.0 and inspect the surrounding batch-enqueue flow for nested MULTI calls. Done means the batch operation no longer raises Redis::CommandError: ERR MULTI calls can not be nested.
