I accidentally dumped a large amount of data into my git repo about a month ago. Pushes stopped working five days ago.

Whenever I try to do a push or a repack -afd, I get:

Counting objects: 14097, done.
Compressing objects: 100% (12947/12947), done.
fatal: Out of memory, malloc failed (tried to allocate 514001492 bytes)

Based on many google searches, I have already tried changing the pack.windowSize to a smaller value (first 128mb, then 50mb) to no avail.

I found the commit that contains this massive amount of data (about 2.7GB, mostly images and massive massive log files; I was not being smart), but at this point I don't know what the appropriate course of action is.

Some further info: This repo gets pushed to a private bitbucket repo which has already received the offending commit and a few more on top of that.
