After some hours after playing Minecraft or another game in 16.10, all the RAM and swap gets filled by an invisible process, and the system freezes with HDD LED on, so it's writing something to the SSD, but nothing happens, and I need to force shutdown and then restart the computer.
To understand these issues, refer to the below screenshots.
Here are two screenshots without Chrome and Java, adding the values on the first picture, it's not 1.7GB. I think some hidden process causes this.
java version "1.8.0_111" Java(TM) SE Runtime Environment (build 1.8.0_111-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
Under OS X and Windows, i had no problems like this... :/
