Correctables and Uncorrectables

I've been having some intermediate service and I saw an alarming amount of correctables and uncorrectables

 

This is what my downstream channels look like:

Re: Correctables and Uncorrectables

morenojose2618, I am having the same issue as you. I've been dealing with this since Oct 2017. My downtime is greater than 8% which is completely unacceptable. I've had 4 regular techs out, 1 manager and his supervisor look into it. All of them have said that the upstream is too high and that is most likely what is causing the issue, but no one has fixed it.
