| |
[1.] One line summary of the problem: High utilisation of memory freezes the computer completely for a long time, with an extremely high access to the hard disk
[2.] Full description of the problem/report: 2a. While booted into the newest mainline kernel only how is the bug reproducible? Its possible to reproduce it with a regular use of Chromium, Firefox and/or LibreOffice, by instance.
In a system, when there is "little" free memory, if we open *some* new links on new tabs on the browser, the system freezes and it's impossible to do anything. Also, there are some worksheets that we can open quickly and without problems when we have a lot of free memory, but when we try to open the same document with little free memory, the system freezes.
Then, sometimes the system becomes very very slow but we can change to a tty and enter some commands to kill Chromium, Firefox or LibreOffice... and the system responds again. Sometimes, after and hour or so the system accept commands again. Although it's also possible "recover" the system using SysRq memory-full-oom-kill(f), but with the consequence of the crashing of one or more applications (it doesn't have to be the one that apparently caused the problem)
In all cases, the hard disk starts to work intensely... until the system has returned to "normal" condition.
2b. Is this a regression? I don't know.
