We re­port on the ef­fects of elec­tron beam ar­rival time and en­ergy jit­ter on the power level and the fluc­tu­a­tions of the out­put of an X-ray FEL os­cil­la­tor (XFELO). For this study, we apply the FEL dri­ven parax­ial res­onator model of XFELO along with an an­a­lyt­i­cal re­flec­tiv­ity pro­file to mimic the phase shift and spec­tral fil­ter­ing ef­fects of Bragg-crys­tals. The thresh­olds for ac­cept­able tim­ing jit­ters and en­ergy jit­ters are de­ter­mined in terms of the fluc­tu­a­tions of the steady-state power out­put. We ex­plore po­ten­tial ways to mit­i­gate the power out­put fluc­tu­a­tions in the pres­ence of un­avoid­able elec­tron beam jit­ters.
