git error - can't push to github - pack-objects died of signal 9

Question

I added some files to the repo, committed, and attempted to push to Github:

$ git add .  
$ git commit -m 'bla'  
$ git push origin master

I am getting an error when I try to push to Github.

Counting objects: 84, done.  
Delta compression using up to 2 threads.  
error: pack-objects died of signal 9  
error: failed to push some refs to 'git@github.com:xxxxx/xxxxx.git'

All was working fine before I went on vacation 2 weeks ago. Nothing has changed in the interim as far as I know. The config file seems to be fine. And git push -f also generates the same errors as above.

What do you mean? SSH key? It had been working fine. Does that "expire" if not used for a couple weeks or something? — Michelle Williamson, Sep 16 '13 at 15:34
you have to set your ssh key to push to github. look at https://github.com/settings/ssh — MZaragoza, Sep 16 '13 at 15:36
Or have you now got some big files? http://stackoverflow.com/questions/7985124/git-push-error-index-pack-died-of-signal-9 — doctorlove, Sep 16 '13 at 15:37
It had been set. I'd been using it for months with no problem. — Michelle Williamson, Sep 16 '13 at 15:37
There are no files over 10 megs except for a file within the .git directory - .git/objects/pack/pack-xxxxxxxxxx.pack. It's 421 Megs. I would think Github could handle that, no? — Michelle Williamson, Sep 16 '13 at 15:55
FWIW, I tried adding the ssh key again and got "Key is already in use". — Michelle Williamson, Sep 16 '13 at 16:01
Sounds like you're getting hit by the [OOM killer](http://stackoverflow.com/q/7180970/1256452). — torek, Sep 16 '13 at 16:09
Turns out @doctorlove was right. There was a 101 Meg error log getting added. Apparently, I'd added the error_log to .gitignore but never removed it from git cache so it was still getting tracked. While I was on vacation, apparently the log topped the 100 Meg limit for the allowed file size. — Michelle Williamson, Sep 16 '13 at 19:15

Try this:

ran into this problem on Cloud 9 workspace free account..Running this command worked! – NiRUS Jul 02 '16 at 11:45
Had a pack-objects died of signal 952 after running the command "git repack -a -d -f --window=250 --depth=250" on a newly constructed svn to git conversion, this fixed that is well. THANKS! – James Eby May 16 '17 at 15:26
Neither this nor `git config --global pack.windowMemory "4096m"` made any difference to me. – Sridhar Sarnobat Sep 28 '21 at 23:19
This solved the problem on a tiny AWS t4g.nano instance I am using for testing. – paradroid May 25 '22 at 20:05

This seems to be working for my bloated repo, unlike the most popular answer. – Sridhar Sarnobat Sep 28 '21 at 23:25
Someone please copy and paste the relevant parts from here: https://git-scm.com/docs/git-repack (but it will make the post long). – Sridhar Sarnobat Sep 28 '21 at 23:31
Correction: this made no difference to the size of mine, though the command did complete successfully. – Sridhar Sarnobat Sep 29 '21 at 20:45

I'm quite convinced you have a local problem and it's nothing to do with GitHub. A git push consists of the following steps:

local: delta compression of objects
net: Writing new compressed objects to remote repo via SSH
net: update refs in remote repo via SSH

Quite clearly, it's the first step that fails. You might be out of memory/swap?

On a FreeBSD box with a lean RAM profile and a large repository with many files, I started getting this error. The /var/log/messages file contained errors like this:

pid 93208 (git), jid 0, uid 1001, was killed: out of swap space

I was able to resolve this by adding a little more swap space temporarily.

In my case it was because the number of files that I wanted to add exceeded 100. If this is your problem you might want to push them in different commits.

Another explanation is that the files you want to push are too large.

Please check the RAM usages, or create more space for swapfile

Had this problem pushing to Gitlab.

Fixed it by adding .* to my .gitignore

i.e. ignored all files/folders e.g. .git beginning with .
