  Type I Be/X-ray binary outbursts are driven by mass transfer from a Be star
decretion disc to a neutron star companion during each orbital period. Treiber
et al. (2021) recently observed non-periodic type I outbursts in RX
J0529.8-6556 that has unknown binary orbital properties. We show that
non-periodic type I outbursts may be temporarily driven in a low eccentricity
binary with a disc that is inclined sufficiently to be mildly unstable to
Kozai-Lidov oscillations. The inclined disc becomes eccentric and material is
transferred to the neutron star at up to three locations in each orbit: when
the neutron star passes the disc apastron or one of the two nodes of the disc.
The timing and magnitude of each vary with the disc argument of periapsis and
longitude of the ascending node that precess in opposite directions.
Calculating the orbital period of the RX J0529.8-6556 system is non-trivial but
we suggest it maybe >300 day, longer than previous estimates.
