In partial (tree:0) clones, git auto-maintenance—specifically commit-graph write --reachable—triggers an unbounded detached lazy-fetch loop, spawning thousands of git processes and consuming extreme memory. Members cover the bug report, a proposed fix to disable auto-maintenance in such clones, and related pack/commit-graph behavior.
