I think this is worth trying to reproduce. The first message you're
seeing about the commit-graph-chain.lock already existing is a
red-herring: it's likely that the last time you tried to generate a
commit-graph, that it hit that same BUG() and left the stale lock laying
around. (I can't remember off the top of my head whether we still run
the atexit handlers upon a BUG(), but even still, I could believe that
some other stray process left it laying around, too).

So, what's interesting is why your commit graph ended up in a state that
it got some commit without all of its parents. If you could reproduce
that state, that would be interesting.

Are you using shallow or partial clones?
