Tried the solution of emptying the metadata folder described above and it eliminates the mentioned problem for just a few days. Done this a couple of times.
Now, i am trying the other proposed solution above of disabling gvfsd: "chmod -x /usr/lib/gvfs/gvfsd-metadata".
[UPDATE]
Here the problem persists. Ubuntu 16.04 LTS.

Waiting for a fix.
