We meet memory leak in 3.4.0 & sambavfs.
With mounting cifs, our application runs,'VIRT' of smbd process will increase untill oom-kill.
using 'fsync/sync' or 'echo 1 > /proc/sys/vm/drop_caches' can't resolve it. With mounting fuse, no memory leaks.
I guess fuse API or samba-gluster-vfs has bug, any advise?
