[optistruct] FATAL ERROR # 9171 32-bit overflow in memory allocation for "lgnnl"

Altair EmployeeHello everyone,
I've encounter an error while using the optistruct solver. It says:
Errors reported during program execution
Error output from the solver:
==============================
*** WARNING: The amount of allocated memory exceeds available RAM - this
may cause significant slowing down of solution progress due to the swapping
out memory to the swap file. It is recommended to use out-of-core
solution to reduce memory requirements.
hwsolver.mesg output from the solver:
==============================
*** FATAL ERROR # 9171 ***
32-bit overflow in memory allocation for 'lgnnl'.
It's very strange that the system didn't report 'not enough memory'. Rather, from the task manager memory window, I observed a steep increase in memory usage up to my max memory (32GB) and then the solver instantly failed.The fem file is quite large, about 3.7GB. I also forced out of core solution. The free disk space is about 600GB. It's a RAID 0 ssd setup btw. Can anyone plz help me on this issue?
Cheers,
Edward

32G ram is not super super big for your 3.7G fem input. RAM module is so cheap now, why not add more memory?
Our smallest compute node has 96G ram here

Wow, you should not play with 3.7G input file on that
Good luck!
