Ubuntu – Chromium and Chrome crashing too often (Ubuntu 14.04)

So, something weird has been happening this week. Chrome and Chromium have started to freeze and subsequently crash. My system keeps going on fine, but Chrome and Chromium freeze and then close up. The only think I can think of that may be causing this is the number of tabs I have open (several dozen).

Anyway, when I open them back up, I get the home page with the option to restore. I click restore and everything starts to load, then it freezes and crashes again, and everything closes. So I cannot restore the session at all. (By the way, is there a way I can get a list of the websites I had open? I cannot restore chrome or chromium without them crashing so I can't access any of my tabs.)

It seems this person is having similar problems: chrome crashing too often in Ubuntu 14.04. I tried the solution proposed there but it did not help. I don't even know how to debug this issue. Any help? Thanks!

Chromium 37.0.2062.120 Ubuntu 14.04 and Google Chrome 38.0.2125.104

EDIT

I ran it from the terminal and got these errors. Will try the limits.conf approach with the reboot tonight.
