Message:
reduce delta cache size to avoid running out of memory on large pack files As reported by Jerome Kasper, got-index-pack would run out of memory while cloning projects like LLVM or the Linux kernel. The delta cache was pushed to its maximum size limit of ~2GB, which is much higher than the default user data limit on OpenBSD. Set the delta cache size limits to values which should result in the cache limiting itself to 128MB or less.
