Problems with "Bitbucket" in "NetBeans 7.4"

Hi, I have a problem ... every time I do push 20MB file on (and sometimes less), I always get this error and I can not upload anything to the repository. I'm using "NetBeans IDE 7.4 (Build 201311011758)" for "WINDOWS 7 64x".

Here the error in an image.

Here the error log.

...
git branch
git remote -v
setting up remote: origin
git push https://bitbucket.org/adventuresdo/one-caribbean-chapter refs/heads/master:refs/heads/master
