Why do i get Stack overflow error in SAS while running stepwise regression

I try to run stepwise regression in sas with 2.9M rows with 300 columns. I am getting below error.

ERROR: Event Stack Overflow. This is probably caused by mis-matched begin and end event calls.

My Code is

* Forward Selection;
proc reg data =work.bs_bm_final_data outest=est1; 
    model  y =  A_004 - A_300 / selection = forward slentry = 0.99 ss2 sse aic; 
output out=out1 p=p r=r; run; quit;

This may be a problem with your version of SAS or something around your machine's configuration. For a server this would be a relatively small dataset but for a consumer desktop or laptop it could be too much.

Can you try running proc glmselect instead and see if it works? The adapted code is below.

proc glmselect data=sashelp.cars;
    model y = A_004 - A_300 / selection=forward(sle=0.99) showpvalues;
    output out=out p=p r=r;
run;

Otherwise, SAS Tech Support would be a good option to contact.
