--- Comment #20 from Denis Lambolez <denis.lambolez at gmail.com> ---
Hi,
Just tested with GlusterFS 3.7.5 and the new package from André:
- samba: 2:4.1.13+dfsg-4ubuntu3glusterfs3.7.5vivid1 
- glusterfs: 3.7.5-ubuntu1~vivid1 

Same behaviour. No change. Here is the dump of the samba panic action script.
Problem is still within libgfapi.so.0.
