At high temperatures, the analytically continued gravitational action of the large AdS black hole is expected to give a leading large-$N$ approximation to the 'slope' of the spectral form factor. When the CFT is put on a $(d-1)$-dimensional spatial sphere of radius $\\ell$, we show that such an evaluation implies unphysical behavior of $Z(\\beta +it)$ at large $t\\gg \\ell$ for $d\\equiv5 \\,({\\rm mod}\\; 4)$.
