Same entry in ps.-Zonaras 758.21. The term is otherwise unattested with this spelling, but presumably comes from the Latin verb exauctorare, "to discharge from service (after sixteen years of service, before the end of the usual term of twenty years)" (Lewis & Short s.v., where examples of such discharge, both honorable and dishonorable, are given). The form e)catori/a is attested in the Tactica of the emperor Leo VI.
