I noticed in our application that during one-off replications futon status shows null% under its output of _active_tasks and remains so for a very long time without any increase in document count.
Count actually remains at zero but the status changes as enclosed below:
BEFORE (n):

AFTER (n+few seconds):

I am not able to understand why this is the case.
Our source db is not that heavy (~500MB) but we do checkpoint our replications. Is null% somehow related to checkpointing ?
Any insight would be of great help. Please write. Thanks !
