Public bug reported:
Upgraded to Zesty about a week ago, and never had this problem in
Yakkety under similar conditions. I usually have a large amount tabs in
Chrome sitting open for days on end. Today, upon attempting to open
probably the 100th tab, the system froze right when the tab was popped.
Chrome is google-chrome-stable 60.0.3112.78-1 from Google PPA.
