Editing pages produces, about one case in several hundred, a whole bunch of duplicate revisions in the page history. This issue most likely cropped up with the recent sync to r41053. Possibly related: [[Wikipedia:Village pump (technical)#Strange error]] (one of the articles there is listed below too). Examples of this phenomenon follow (these are all sets of consecutive diffs): http://en.wikipedia.org/w/index.php?title=2008&diff=239778370&oldid=239778233 http://en.wikipedia.org/w/index.php?title=2008&diff=next&oldid=239778370 http://en.wikipedia.org/w/index.php?title=2008&diff=next&oldid=239778382 http://en.wikipedia.org/w/index.php?title=Argentina_national_football_team&diff=239779781&oldid=239779072 http://en.wikipedia.org/w/index.php?title=Argentina_national_football_team&diff=next&oldid=239779781 http://en.wikipedia.org/w/index.php?title=Argentina_national_football_team&diff=next&oldid=239779793 then http://en.wikipedia.org/w/index.php?title=Argentina_national_football_team&diff=next&oldid=239779795 http://en.wikipedia.org/w/index.php?title=Argentina_national_football_team&diff=next&oldid=239779818 http://en.wikipedia.org/w/index.php?title=Stone_Cold_Steve_Austin&diff=prev&oldid=239780164 http://en.wikipedia.org/w/index.php?title=Stone_Cold_Steve_Austin&diff=next&oldid=239780164 then http://en.wikipedia.org/w/index.php?title=Stone_Cold_Steve_Austin&diff=next&oldid=239780168 http://en.wikipedia.org/w/index.php?title=Stone_Cold_Steve_Austin&diff=next&oldid=239780227 then http://en.wikipedia.org/w/index.php?title=Stone_Cold_Steve_Austin&diff=next&oldid=239780234 http://en.wikipedia.org/w/index.php?title=Stone_Cold_Steve_Austin&diff=next&oldid=239780333 http://en.wikipedia.org/w/index.php?title=United_Church_of_Christ&diff=239780794&oldid=239780725 http://en.wikipedia.org/w/index.php?title=United_Church_of_Christ&diff=next&oldid=239780794 http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=239774277&oldid=239774244 http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774277 http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774278 then http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774418 http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774493 http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774497 http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774505 then http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774909 http://en.wikipedia.org/w/index.php?title=Tottenham_Hotspur_F.C.&diff=next&oldid=239774964 http://en.wikipedia.org/w/index.php?title=Modern_Sounds_in_Country_and_Western_Music&diff=239782219&oldid=239782062 http://en.wikipedia.org/w/index.php?title=Modern_Sounds_in_Country_and_Western_Music&diff=next&oldid=239782219 http://en.wikipedia.org/w/index.php?title=Modern_Sounds_in_Country_and_Western_Music&diff=next&oldid=239782221 http://en.wikipedia.org/w/index.php?title=Modern_Sounds_in_Country_and_Western_Music&diff=next&oldid=239782223 http://en.wikipedia.org/w/index.php?title=Modern_Sounds_in_Country_and_Western_Music&diff=next&oldid=239782224 http://en.wikipedia.org/w/index.php?title=Viru_Viru_International_Airport&diff=239782313&oldid=239782117 http://en.wikipedia.org/w/index.php?title=Viru_Viru_International_Airport&diff=next&oldid=239782313
Most of the diffs above are to do with [[User:II MusLiM HyBRiD II]], who just complained about the problem described in the VPT thread, see http://en.wikipedia.org/w/index.php?title=User_talk%3AII_MusLiM_HyBRiD_II&diff=239782852&oldid=239263364 .
Seems like the user kept retrying and getting errors. What bothers me is that on failure, the entire transaction should have been rolled back.

Bah, didn't find this bug when searching, bad summary ^_^ Per closed bug comment, I was able to duplicate this with only three tries (Opening the [rollback] link a few times in new tabs): http://test.wikipedia.org/w/index.php?title=Sandbox&diff=63617&oldid=63616&diffonly=true
Should be fixed now, as of r41089.
