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.
When Chrome window has focus press Shift>+Esc to bring up process manager:
I've ententionally narrowed the Task name width to hide my gmail inbox name but you can see it is using over 400 MB of RAM. In this screen Chrome is using 1.7 GB of RAM simply surfing the net with 10 Tabs opened.
Your screen only shows the Chrome name but this screen shows each opened Tab name to track down the offender. In my case if I wanted to free up RAM I would close gamil.com.
The second large RAM user is Earth-Sunrise website that has a comment section. Some websites with comment sections can burn up lots of RAM, in testing over 1 GB per tab over a few hours. Simpy refreshing the Tab brings the usage back down to ~100 MB.
The tool VisualVM will display Java memory usage and other information:
You can download it from github: (VisualVM)
