Hi, Since 2.43.0 I'm seeing the following error message when I fetch from a remote: $LC_ALL=C git fetch --all remote: Enumerating objects: 446, done. remote: Counting objects: 100% (446/446), done. remote: Compressing objects: 100% (135/135), done. remote: Total 446 (delta 328), reused 415 (delta 311), pack-reused 0 Receiving objects: 100% (446/446), 432.84 KiB | 1.01 MiB/s, done.

Another git process seems to be running in this repository, e.g. an editor opened by 'git commit'. Please make sure all processes are terminated then try again. If it still fails, a git process may have crashed in this repository earlier: remove the file manually to continue. Observations: - repo and gitforge independent - only happens when fetch.writeCommitGraph is turned on - git gc cleans up the stale lock file - I think this is only happening when multiple branches on the remote have changed I do have protocol.version set to 2. I tried replicating the issue with an example but failed so far. Does that ring a bell somewhere? Where should I start poking?
