Hi,
We just started using Alfresco Community 4.2.d in production and have noticed a weird issue. It seems that for some reason the categories tree in the document library seems to lose it's link to the categories in the documents and folders. If I look at the rules, documents and folders I see the category still there. If I click on the node in the category tree I get a single red line with 0 results found in white bold text. This is different than clicking on a category that has nothing linked to it, that returns a No documents found message. I found a short term solution, remove and re-add the category in the Category Manager, then edit and re-run the rule on the folders for attaching that category. Obviously as we get more categories and more folders this will become and unmanageable task.
What could be causing this, is it an issue with the SOLR indexes? If so what log file do I look into to investigate this?
