HTTP Error 431 when pulling/pushing

[David Demelier]

Hello,

For the first time, I need your help. I can't figure out why today some
of my repositories are unable to be pulled or pushed. I get the
following error:

$ hg pull 
pulling from http://hg.malikania.fr/irccd/3.0.0
searching for changes
abort: HTTP Error 431:

It does the same if trying to push. My webserver configuration has not
changed, and nothing was updated at all.

Regards,
