Possible solutions are to increase your resources or removing the synthetic keys that are not useful to the data model.

The engine may end up using excessive amount of time and/or memory when the number of composite keys/Synthetic Tables increase, depending on data amounts, table structure and other factors. Unfortunately the actual limitations are virtually impossible to predict, which leaves only trial and error as a practical method to determine them.Article on Synthetic Keys
