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

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
