title: Bitbucket: git push error: pack-objects died of signal 13
body: <p>I tried to push my local repo to my origin branch on Bitbucket, and kept failing to push it. The error shows like below.</p>
  
  <pre><code>Counting objects: 2309, done.
  Delta compression using up to 4 threads.
  Connection to bitbucket.org closed by remote host.
  fatal: The remote end hung up unexpectedly
  Compressing objects: 100% (2295/2295), done.
  error: pack-objects died of signal 13
  error: failed to push some refs to .... 
  </code></pre>
  
  <p>I already tried </p>
  
  <pre><code>git config http.postBuffer 5242880
  </code></pre>
  
  <p>and the result showed the same error. I also tried to change my setting from https to ssh, but still there was the same error. </p>
  
  <p>I guess it may be because I push large files to my remote repository. I have not requested any updates for one month, and only done pull requests to update my local repo.</p>
