Question on loading a big file

[Sebastian Calvo]

Hi all, 

Currently, I am working with some elements of a group. Each element is stored as a map(S,S, {....... }) where S = QQ[x0,...,x7]. I use 120 generators + identity to generate more elements with a for loop to obtain 6141 on the first iteration and then 169,941 on the second iteration. I have saved these group elements in a file by 

"G" << "G = " << toString G << endl << close;

with a size of 42 MB. However when I try to load this file, the program is killed and I get a "Process M2 interrupt". In the past, I have gotten error codes to increase initial heap size but this isn't one of those. 

Can anyone shed light on what is happening? In particular, how is Macaulay2 able to generate the elements "manually" if I run the code but if I ask it to pull those same elements from a file, it isn't able to? 

Thanks!
