Question #251723 on Graphite changed:

Status: Needs information => Answered
Jason Dixon proposed the following answer:
I've seen this when carbon-cache is blocking on writes. If you're using
relays look for the existence of
carbon.relays.*.destinations.*.queuedUntilConnected
and carbon.relays.*.destinations.*.fullQueueDrops metrics.
Also, check your carbon.agents.*.cache.queues metrics.
