A recent update to the mediawiki multiversion scripts broke the abstract dumps; a bug report and a fix have been submitted so I expect this to get taken care of by Monday at the latest and hopefully over the weekend. In the meantime no new jobs for small wikis will be produced; I'll start those up again once the fix is in, as well as rerunning the abstract dumps where it failed. Currently running jobs will run to completion.

The fix was deployed a little while ago, most dumps were fixed up and all processes are running again. There's still a couple more runs that need to be fixed up, that will happen over the next day or so.
