Update 1/11/16: Current version of Chrome 47.0.2526.106 resolves this behavior.
I’ve been experiencing some short machine freezes while using both OS X Yosemite and El Capitan. Could not figure this out for a while and I think I found the culprit.
These short freezes last about 2-4 seconds, only appear while Chrome (production) is running, and appear to freeze not just Chrome but the entire machine.
When Chrome runs a software update in the background, it throws the following message in the console "triggered DYLD shared region unnest for map"
.
