Dear Anoop, thank you very much for your detailed explanation. > I think you are hitting a bug[1] from vfs module for GlusterFS inside Samba during a realpath() > call. > > This regression got in when glfs_realpath() was modified in GlusterFS[2] to correctly handle memory > allocation and corresponding freeing of string arguments.

I'm using GlusterFS 3.12.3 from the GlusterFS Ubuntu PPA [1]:: $ apt-cache policy glusterfs-client glusterfs-client: Installed: 3.12.3-ubuntu1~xenial1 Candidate: 3.12.3-ubuntu1~xenial1 Version table: *** 3.12.3-ubuntu1~xenial1 500 500 http://ppa.launchpad.net/gluster/glusterfs-3.12/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status 3.7.6-1ubuntu1 500 500 http://nova.clouds.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages 500 http://archive.ubuntu.com/ubuntu xenial/universe amd64 Packages So this should contain the fix already? Or is the fix Samba-side?
