I am trying to fit a growth curve model with multiple indicators and distal outcome using known classes. When I run the model, I get the following messsage:

*** FATAL ERROR
THERE IS NOT ENOUGH MEMORY SPACE TO RUN THE PROGRAM ON THE CURRENT
INPUT FILE. THE ANALYSIS REQUIRES 2 DIMENSIONS OF INTEGRATION RESULTING
IN A TOTAL OF 0.22500E+03 INTEGRATION POINTS. THIS MAY BE THE CAUSE
OF THE MEMORY SHORTAGE. YOU CAN TRY TO FREE UP SOME MEMORY BY CLOSING
OTHER APPLICATIONS THAT ARE CURRENTLY RUNNING. ANOTHER SUGGESTION IS
CLEANING UP YOUR HARD DRIVE BY DELETING UNNECESSARY FILES.

Do you have any suggestions for how to deal with this?

There is a section in Chapter 13 of the Mplus User's Guide that lists suggestions for using numerical integration. You can try reducing the number of integration points per dimension from the default of 15 to 7 or 10. This is done through the INTEGRATION option in the ANALYSIS command.
