Do you have the reproduction steps for this? If I run git -c protocol.version=2 fetch --tags \ https://chromium.googlesource.com/chromium/src \ +refs/heads/*:refs/remotes/origin/* --depth=1 repeatedly in the same repository, it succeeds. (And I've checked with GIT_TRACE_PACKET that it uses protocol v2.)
