It seems that we're getting a tcp disconnect (ECONNRESET) on when doing that shutdown() on postcopy_qemufile_src. The one from commit 6621883f93 ("migration: Fix potential race on postcopy_qemufile_src"). I'm trying to determine why that happens when other times it just returns 0 as expected. Could this mean that we're kicking the dest too soon while it is still receiving valid data?
