They are merely a different name for I think CRCs listed on the GEA service test results.
That makes sense. Assume 'ingress' is for download and 'egress' is for upload?
It's very odd however to have thousands of CRCs, assuming that is what they are, without any ES to go with them.
@The_nuke, please can we have a screenshot showing the error counts to help better understand what is happening here.
