error 16 is EBUSY: meaning it can't take a lease to do work on the bucket.
This usually happens when another entity (e.g., a running radosgw process)
is working on it at the same time. Either something took the lease and
never gave it back (leases shouldn't be indefinite, usually are being taken
for a short period but are renewed periodically), or there might be some
other bug related to the lease itself. I would start by first figuring out
whether it's the first case or the second one. On the messenger log there
should be a message prior to that that shows the operation that got the -16
as a response (should have something like "...=-16 (Device or resource
busy)" in it). The same line would also contain the name of the rados
object that is used to manage the lease. Try to look at the running radosgw
log at the same time when this happens, and check whether there are other
operations on that object.
One thing to note is that if you run a sync on a bucket and stop it
uncleanly in the middle (e.g., like killing the process), the leak will
stay locked for a period of time (Something in the order of 1 to 2 minutes).
