Hello.
I'm finding strange issues when trying to decompress the 7z version of this dump for the French Wikipedia:
http://dumps.wikimedia.org/frwiki/20120430/
At some point around 3M revisions the 7z process stalls. After a long time (few hours) it recovers normal execution, but then stalls again around 55M revisions to never recover normal cruise again.
Maybe there are some issues with frwiki dumps, since I can see that subsequent processes are experimenting failures (in May and June).
I'm now checking with the previous dump (http://dumps.wikimedia.org/frwiki/20120404/). I'll let you know in case I find any more problems.
Best, Felipe.
It apparently decompresses ok.

The content might be completely bogus, though. It'd need further checks.
