I'd guess the latter. You are correct: 15:27:24.264161 git.c:415 trace: built-in: git pack- objects --keep-true-parents --honor-pack-keep --non-empty --all -- reflog --indexed-objects --unpack-unreachable=2.weeks.ago --local -- delta-base-offset .git/objects/pack/.tmp-17617-pack > If so, can you try running it under gdb and getting a stack trace?
