--- Comment #5 from Kyle Johnson <kjohnson at gnulnx.net> ---
I may also be experiencing this bug.

Distributed volume w/ 3.7.14, no patches.  One server is FreeBSD 10.x, the
other is CentOS 6.  Both bricks are ZFS backed.

===
[root at colossus2 ~]# gluster volume info ftp

Volume Name: ftp
Type: Distribute
Volume ID: f3f2b222-575c-4c8d-92f1-e640fd7edfbb
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: 192.168.110.1:/tank/bricks/ftp
Brick2: 192.168.110.2:/ftp/bricks/ftp
Options Reconfigured:
performance.client-io-threads: on
cluster.weighted-rebalance: off
performance.readdir-ahead: on
nfs.disable: on
===

After approximately 24 hours of heaving reading on the client (copying 93728
files totaling 1.4Tb out of the fuse mount point, elsewhere on the system to a
non-gluster space) , I found that the glusterfs process was consuming all
system memory, including swap, approximately 34Gb.  Remounting the fuse volume
freed up the memory.

Let me know if you need anything else.
