OpenCL compile error for high resource utilization

Hello,

I encounter compile error (Error (23031): Evaluation of Tcl script import_compile.tcl unsuccessful) when my resource utilization is huge. My estimated resource usage is :

+--------------------------------------------------------------------+

; Estimated Resource Usage Summary ;

+----------------------------------------+---------------------------+

; Resource + Usage ;

+----------------------------------------+---------------------------+

; Logic utilization ; 65% ;

; ALUTs ; 39% ;

; Dedicated logic registers ; 29% ;

; Memory blocks ; 59% ;

; DSP blocks ; 79% ;

+----------------------------------------+---------------------------;

I have attached the compile log. I have seen previous threads in the forum and this error might be because of less RAM. I have allocated 20GB of RAM and 60GB of swap for this compilation. Do you think my error is still because of less RAM?

My log file ends with the following error

Error: Quartus Prime Compiler Database Interface was unsuccessful. 1 error, 0 warnings
