Windows error 01

Description of problem:
SMBD thread panics when a file operation performed from a Windows, Linux or OS
X client when the share is using the glusterfs VFS module, either on its own,
or in conjunction with others i.e.:
>    vfs objects = catia fruit streams_xattr glusterfs


Gluster volume info:
Volume Name: mcv01

Volume ID: 1580ab45-0a14-4f2f-8958-b55b435cdc47
Status: Started

Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: mcn01:/mnt/h1a/mcv01_data
Brick2: mcn02:/mnt/h1b/mcv01_data
Brick3: mcn01:/mnt/h2a/mcv01_data

Options Reconfigured:
features.quota-deem-statfs: on
nfs.disable: on
features.inode-quota: on
features.quota: on
cluster.brick-multiplex: off
cluster.server-quorum-ratio: 50%


Version-Release number of selected component (if applicable):
Gluster 6.3
Samba 4.10.6-5

How reproducible:
Every time

Steps to Reproduce:
1. Mount share as mapped drive
2. Write to share or read from share

Actual results:
Multiple error messages, attached to bug
In OS X or Linux, running 'dd if=/dev/zero of=/mnt/share/test.dat bs=1M
count=100' results in a hang. Tailing OS X console logs reveals that the share
is timing out.

Expected results:
File operation is successful

Additional info:
Gluster client logs, and SMB debug 10 logs attached
