We have a large document library with about 1.4 million records. I'd say on average each doc has about 5 versions however, only the list (meta) data changes. Never the actual document. This doc library keeps turning it's versioning off every time I turn it on. Usually overnight. Although it was once per week not too long ago and has gotten progressively worse over time.
We've contacted MS Support and after about 2 weeks of attempts, it is still not fixed. Most of their advise revolved around using PowerShell to set versioning and testing on other libraries. One interesting find was that versioning is working on all other doc libraries on all sites. It seems to only be this large library that has the issue. They ran out of ideas and we are not told to decrease the size of the library is the only option.
Has anyone else ran into this issue? Any ideas how to overcome it and keep versioning on indefinitely?
This is a plain vanilla doc library. No doc control or retention policies are enabled.
