What is your -w size? Recently one user report that windows might have
on top of object cache. But all the QEMU and sheepdog logs didn't report
broken. So I suspect that there is latent bug hidden in relcaim code of
cache. Reclaim code will triggered very often when the cache is full and it
reclaim the space.
