Bug 957657

Description of problem:
=======================

glusterfs fuse crashed on client.


Version-Release number of selected component (if applicable):
=============================================================

[root@darrel test-nfs]# rpm -qa | grep gluster
glusterfs-debuginfo-3.4.0.1rhs-1.el6rhs.x86_64
glusterfs-fuse-3.4.0.1rhs-1.el6rhs.x86_64
glusterfs-3.4.0.1rhs-1.el6rhs.x86_64
[root@darrel test-nfs]# 

Steps Carried:
==============
1. Created 6*2 distriubuted-replicate volume
2. Mounted on client (both fuse and nfs mount)
3. Created test-fuse and test-nfs directories on fuse and nfs mount respectively.
4. Ran script.sh on both fuse and nfs test directories. Script does the directory and file creation, dd etc.
5. Ran the areequal checksum on the fuse mount. It reported the following:

[root@darrel test-fuse]# /opt/qa/tools/system_light/arequal/arequal-checksum -p /mnt/fuse 
md5sum: /mnt/fuse/test-nfs/test_entry_self_heal/file.11: Transport endpoint is not connected
/mnt/fuse/test-nfs/test_entry_self_heal/file.11: short read
ftw (-p) returned -1 (Success), terminating
[root@darrel test-fuse]# 


Checked the client log and found the following:
