[Openstack] High I/O on idle Swift devices

I built 4 node test swift cluster and stored one 100MB file. Cluster was
running 24 hours without any load. During this period, I can see
constant read I/O of 3MB/s on each swift device. When I shutdown
object-server I/O goes to zero. I've also increased replicator's
run_pause to 300 sec, but it didn't help at all.
Is that an expected behavior? What causes such a high I/O on idle
system. How can I troubleshoot this?
