Hello, I seem to have a serious memory leak on my system (Lenovo W550s) - the memory usage seems to slowly but more or less steadily keep increasing.
This is a more or less normal (I think) desktop installation of Sid, running Xfce4. Typical applications used are Firefox (currently with just one extension: uBlock Origin), LibreOffice Writer, Sylpheed, Xfce4 Terminal, and Liferea, all from the official repos. I used to have 8 GB on the system, and it would start to thrash at about 7+ GB usage. I recently ugrade to 16 GB; memory usage is currently over 8 GB, and it seems to be slowly but steadily increasing. I have never been able to wrap my head around linux memory usage reporting. htop currently reports about 8.13 GB used (up from about 8.03 when I began this email). I sorted the processes by PERCENT_MEM, and here are the leaders (VIRT / RES / SHR): A half dozen or so Xorg processes: 4340M / 2947M / 90948 Numerous 'firefox' processes: 5102M / 1068M / 369M. Some soffice.bin processes: 1096M / 301M / 128M. A bunch more '/usr/lib/firefox/firefox' processes: 27.2G / 213M / 88620. Some webkit processes: 100G / 212M / 143M. Some liferea processes: 84.3G / 198M / 112M A bunch *more* '/usr/lib/firefox/firefox' processes: 2835M / 186M / 127M And a bunch *more* '/usr/lib/firefox/firefox' processes: 2456M / 180M / 150M And then several more bunches of '/usr/lib/firefox/firefox' processes, with values of the same orders of magnitude to the preceeding ones. My understanding is that it's the RES and SHR values that are important, not the VIRT ones. I have the impression that the Xorg values are high. I saw recommendations to use xrestop to check things like pixmap usage. I don't really know much about this, but currently the total pixmap usage is about 360M, mostly used by a Writer process, and about 40M for Xfwm4 and 30M by Firefox. Any ideas? Celejar
