  We examine the necessary and sufficient conditions for a complete symmetric
equipartite digraph $K_{n[m]}^\ast$ with $n$ parts of size $m$ to admit a
resolvable decomposition into directed cycles of length $t$. We show that the
obvious necessary conditions are sufficient for $m,n,t \ge 2$ in each of the
following four cases: (i) $m(n-1)$ is even; (ii) $\gcd(m,n) \not\in \{1,3\}$;
(iii) $\gcd(m,n)=1$ and $4|n$ or $6|n$; and (iv) $\gcd(m,n)=3$, and if $n=6$,
then $p|m$ for a prime $p \le 37$.
