This issue has been quite a challenge for us. Just about identical workflow. XDCAM 35mb Multicam edit. 3 systems pulling from XSAN, 2 angles so not even that stream intensive. Green flicker of death when in open sync mode or in trim mode. To those saying its an AJA thing, I would have agreed with you but we can reproduce without any hardware. Basically a stripped down FCP with now output hardware. I would LOVE to see a solution somewhere. Our best success was to drop the cache down to 80%. We can at least save before it fully crashes. Anyone have any solid luck with this annoyance? The silence of success from the Avid rooms are deafening.
