I have not seen the problem since Monday, which is pretty much the first time ever I work more than 3 days without seeing it. Ok, it can be a coincidence. Notice that I did not change anything related to my work behavior. However, I did do two things: _ Update the kernel to 4.7.2; and _ Created 50 dummy files with 3.0 GiB each. Can anyone, please, tell me if these things seems to be correlated? Best regards, Ronan Arraes
