Thanks for your inputs Michael and Gary, Gary, the case you mention makes me wonder if this is a tag problem or the way binaries are being tagged every day. I was chatting with Andy and he mentioned to me that in general Nexus3 reports so many docker issues.
We confirmed this is not relates to a disk capacity issues since we have still about 3TB of free space. I am trying something now which I don't guarantee might fix our issue, but we could give it a shot at least. I have upgraded https://nexus3ap.onap.org/ to version 3.11.0 and see how it behaves. If everything goes fine and that version is stable, we should upgrade nexus3.onap.org too so that we are at least on the latest version. Can I get your thoughts on this? Thanks!
