[Gluster-users] Gluster samba panic?

[Diego Remolina]

I actually had this problem with CentOS 7 and glusterfs 3.7.x

I downgraded to 3.6.x and the crashes stopped.

See https://bugzilla.redhat.com/show_bug.cgi?id=1234877

It may be the same issue.

I am still in the old samba-vfs-glusterfs-4.1.12-23.el7_1.x86_64 and
glusterfs-3.6.6-1.el7.x86_64 on that machine and see no crashes.
