[Xmldatadumps-l] Occasional duplicate page records in XML data dumps

Hi. I've noticed that some June XML data dumps have duplicate <page> records, usually at the end of the dump. Anyone know if this is intentional? One or two duplicate records is benign, but I'm slightly concerned that it may be a symptom of a larger problem. I've been working with the XML data dumps for over 3 years, and haven't seen this before.[1] I list some examples below. They're only from the Swedish wikis and Spanish Wikipedia (which is what I started looking at this week) Let me know if you need any other info, and I'll be happy to provide. Finally, for questions like these, is it best to email the mailing list, create a task in Phabricator or do both? Thanks. [1]: It may have started as recently as 2015 April. I stopped looking at dumps shortly before the May problems with the dump server. ---- Example 1: URL: http://dumps.wikimedia.org/svwikiversity/20150602/svwikiversity-20150602-pa… Title: Audi m8 ID: 18942 SHA1: gd16v3qkmjr2w2j35zhqitjfg97igjt) Note: Last article in dump.
