From what I can tell - it happens from both adminhtml and frontend.
Magento version 2.0.2 with default theme and pretty much default setup(except 3 store views and couple of products imported).

[vzaporozhets]

@werdlv, are you able to see frontend/admin while receiving such errors? Which OS is used?

[jsakars]

@vzaporozhets yes, both admin & front-end are accessible and seems to work fine in general. Ubuntu 14.04 is used along PHP7 and Nginx

I am experiencing same issue, as a result the main menu in frontend not showing up

[vzaporozhets]

@lutpiero I noticed the same issue when installed M2 on Windows using "localhost" in the base URL. Adding any alias with domain part (ex. "magento.local") to "hosts"-file resolve this issue and M2 works just fine. But do not forget to use this alias for the base URL while installing Magento.

@werdlv Can you tell a bit more about store views configuration?

[jsakars]

@vzaporozhets there is nothing specific about store views - en, ru, lv for example

[vzaporozhets]

@werdlv we can't reproduce this problem with 2.0.4 using the same environment. Can you please re-test this issue with latest version and report more details if it is still faced.

[adragus-inviqa]

@vzaporozhets - you're kidding, right? :)
I always get those. My logs are full of it. So much so that I've come to accept it as a feature. Unfortunately, I'm not looking at system.log anymore. Nothing critical to see in there. Just a lot of noise.

[jsakars]

issue still persists

[medinadato]

Yes, the issue still persists. I've installed Magento 2.0.5 and the errors keep popping up. Pretty disappoint having an application with those kind of bugs out of the box.

[vzaporozhets]

@adragus-inviqa No, I'm not kidding :-) I checked logs of our environment with PHP7/nginx where 2.0.X has been tested and didn't find such messages. If Magento works and all layouts are fine - this is fail error reporting which need to be fixed. We just need to reproduce it - I'll keep you informed.
