RAM deficiency after recent large Manjaro update?

[stozi]

A couple days ago there was a major-ish Manjaro update. Since then, half of my Chromium tabs and extensions are constantly crashing. I use quite a bit but this wasn't happening before.

$ cat /sys/block/zram0/disksize  
6075875328

This means 6 Gigs right? Don't get what the problem is 

# swapon /dev/zram0

says it's already busy.

I am using Manjaro without zram, and I have not had any problems with the new update.
