I have this problem as well. I'm running Chromium on Ubuntu 16.04 and the "browser" process increases memory usage over time, regardless of activity or other tabs memory usage.
It is not as grave as 13GB in 4 hours, but I'm running only a couple of tabs with no extensions and still see the browser processes bloating memory. Generally, after 24h of execution it takes over 1GB of memory and keeps increasing, even if killing all the tabs and extensions. My current session has only two tabs active, each with around ~100MB and no extensions. This is used for work, so there is no facebook or youtube browsing, no flash. ** Attachment added: "depiction of browser process memory usage with no other tabs or extensions" https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1751137/+attachment/5070289/+files/chromium%20memory.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1751137 Title: Severe memory leak: 13 GB RAM in 3-4 hours Status in chromium-browser package in Ubuntu: Incomplete Bug description: I am on Bionic with a new Lenovo X1 Yoga (2nd gen., current model) with 16 GB RAM. For some weeks now chromium-browser has a severe memory leak. It fills up 13 GB of the 16 GB RAM in 3-4 hours, independent how frequently I use the browser in this time. I use many tabs (~20-30) and as add-ons I use Adblock Plus, Ulmon CityMaps2Go, and Google Dictionary. Next time Chromium blows up I will remove one of them to find out if an add-on is the culprit. When Chromium fills up the memory sometimes the computer gets simply slow, sometimes the rendering engine goes away (all tabs are simply solid grey instead of shown their web page), and/or there are pop-up windows about add-ons having crashed. To get rid of the blown-up Chromium I run "top" in a terminal window, sort by memory occupation (Shift + M) and kill the process making the first place in the list (K, then 2 times Enter). This blown-up process is always the master process of Chromium, not one of the tabs, as killing this process pulls down Chromium completely (and frees the RAM).
