I'm using Magento 2 CE Version 2.1.0
I already referred Magento SO post with the same error.
When I'm going to Edit Any of the Product then while loading it's giving this error. Below are the details of log files

Regarding the debug file
So the messages like this
main.DEBUG: cache_invalidate
in Magento 2 are not errors, there are only debug messages to tell that the cache is invalidated (which is not a problem nor an error).Regarding the system file
So the messages like this
Broken reference: the 'block1' tries to reorder itself towards 'block2'
is not a real error either. As you can see from this github issue:I reckon there was a lot of errors like this in the logs in the early stable releases as you can see from those two issues:
So if you wanna get rid of them, I reckon you should update to the last version. Seems like Magento fixed it in the
develop
branch but I'm not sure if the bug fixes are part of 2.0.8/2.1.1 already.
