So if your existing pack is ~2GB, repack will fail. Also, I think that setting window-memory to 0 means no limit, which is not what you want. One value I have seen suggested is 256m. In my experience, peak memory consumption of repack is proportional to the value of --window, so you might want to try tweaking that. There are quite a few config parameters that affect the memory consumption of repack. -- David Barr -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
