I run a tool (http://svick.aspweb.cz/CatWatch.aspx) that watches additions and removals of pages to categories. It seems that every few days, several hundred members of [[Category:Stub-Class Academic Journal articles]] are removed from the listing of the category and later again readded, while nothing changes on the actual member pages or the template used.
Most recent incidents:
3.4.2010 21:36 1314 pages were removed
4.4.2010 10:22 1314 pages were added
6.4.2010 22:16 821 pages were removed
Currently, for example [[Talk:American Economic Review]] isn't listed in the category, but the page itself shows that it is member of the category. The page itself hasn't changed for several months.
