Windows – Git on Windows, “Out of memory – malloc failed”


Have run into a problem with repository and tried almost every possible config setting found out there eg. pack.WindowMemory etc etc

I believe someone has checked in a large file to remote repository and now each time I try and pull or push to it, GIT tries to pack it and runs out of memory:

Auto packing the repository for optimum performance. You may also
run "git gc" manually. See "git help gc" for more information.
Counting objects: 6279, done.
Compressing objects: 100% (6147/6147), done.
fatal: Out of memory, malloc failed (tried to allocate 1549040327 bytes)
error: failed to run repack

Have tried git gc & git repack with various options but keeps returning same error.

Almost given up and about to just create a new repo but thought I'd ask around first 🙂

Best Solution

I found a solution Here that worked for me.

In .git/config file (client and/or server) I added the following:

  packedGitLimit = 128m
  packedGitWindowSize = 128m

  deltaCacheSize = 128m
  packSizeLimit = 128m
  windowMemory = 128m
