We were looking at anon_conns and accepting_conns without holding the lock (deleted_lock is not sufficient). Drop this test, and move the decrements: - inc when we add to conns or anon_conns (no changes there) - dec when we remove from deleted_conns (several different paths!) Fixes: https://tracker.ceph.com/issues/49237 Signed-off-by: Sage Weil <sage@newdream.net> (cherry picked from commit d51d80b) Signed-off-by: Gerald Yang <gerald.yang.tw@gmail.com>
