> After running v5.2.0 over the weekend on one of our prod hosts, I've noticed that the RES memory from top grew to 21g (the corresponding RES memory on a v5.0 prod host is 10g). Looking at the memory dump, it seems that it might be leaking 4K iobuffers. The memory dump shows as much as 10g of 4K buffers allocated/in-use (on the corresponding v5 host, the 4k buffers are only at 300MB level)
