error: pack-objects died of signal 9

git was killed by host monitor process or oom due to memory usage. Check syslog for OOM entries.

git command running under user 'git' with gitlab installed looks for configuration in following places:

• current git repo
• /etc/gitconfig
• /var/opt/gitlab/.config/git/config
• /var/opt/gitlab/.gitconfig

This is a user config gile, and file is generated form /opt/gitlab/embedded/cookbooks/gitlab/templates/default/gitconfig.erb

But if git binary from gitlab is used

sudo -u git -H "/opt/gitlab/embedded/bin/git" config -l

then, file /opt/gitlab/embedded/etc/gitconfig is used. To modify this file:

gitlab.rb

omnibus_gitconfig['system'] = { "receive" => ["fsckObjects = true"],
                                "core" => ["packedGitLimit = 40m", "packedGitWindowSize = 40m"],
                                "pack" => ["deltaCacheSize = 40m", "packSizeLimit = 40m", "windowMemory = 40m", "threads = 1"] }

Test config:

gitlabctl show-config

Regenerate config:

gitlabctl reconfigure

sudo -u git bash
cd /var/opt/gitlab/git-data/repositories/{namespace}/{repository}.git
git gc --aggressive
