Git: erreur: RPC a échoué; resultat = 22, code HTTP = 411

Symptômes:

Git a soudainement refusé de pousser un repository (pour github dans mon cas):

$ git push Counting objects: 9292, done. Delta compression using up to 8 threads. Compressing objects: 100% (2136/2136), done. error: RPC failed; result=22, HTTP code = 411 fatal: The remote end hung up unexpectedly Writing objects: 100% (8222/8222), 1.27 MiB | 837 KiB/s, done. Total 8222 (delta 6060), reused 8181 (delta 6033) fatal: The remote end hung up unexpectedly Everything up-to-date 

Voici ce qui a aidé, la commande suivante augmente le tampon git à 500mb:

 git config http.postBuffer 524288000
