[Bug 1642413] [NEW] Chromium uses ~100% of all cores, locks up, and does not exit correctly

 

You have been subscribed to a public bug:

whether or not extensions are enabled, after an indeterminate amount of
time chromium locks up(tabs are still rendered but browser cannot create
new tabs, or navigate in existing ones) and the main process begins
using 200-270% of my three cores, chrome task manager shows that no tab
is using any memory and when chromium is exited the main thread does not
quit and must be killed.

I have reinstalled, disabled extensions/plugins, etc... nothing seems to
remedy this issue.

I memtested my memory and it was fine.


It started happening october 2016
