Message number: 485
Message text: The ranking list cannot be created due to insufficient memory
The ranked list cannot be created because there is not enough memory.
The memory consumption of the roll area is so large that the system
cannot fulfill any more requests for memory. Since the algorithm for
creating ranked lists requires memory, but there is no more memory, the
list simply cannot be created.
Call the ranked list at an earlier point in time in debugging mode.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
