Hello
Try setting these values and restart the instance.
ztta/roll_extension = 64000000000
abap/heap_area_total = 5000000000
abap/heap_area_nondia = 5000000000
ztta/roll_area = 10000000
abap/buffersize = 400000000
If possible restart the primary and the shadow instance after cleaning the shared memory segments.
Regards
RB
