    Description

      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)

      -bash-4.1$ sudo grep "memory/ioBufAllocator\[5\]" traffic.out 
               9421979648 |         9421180928 |       4096 | memory/ioBufAllocator[5]
               9431416832 |         9429147648 |       4096 | memory/ioBufAllocator[5]
               9700900864 |         9692045312 |       4096 | memory/ioBufAllocator[5]
