Run two CGIs simultaneously and Ajax to read updated value from CGI1

Flow of program:
C based CGI is used

CGI1:
-Gets called when user hits upload button(submit) ie form action = CGI1
-Does the file upload (copy to a directory etc)

JS, Ajax fucntion:
-A JS function is called when user hits upload button
-The JS function opens an Ajax request for CGI2
-Ajax keeps polling CGI2 for updated value

CGI2:
-Contains:
system ("some cmd to get directory size");

Issue:
Ajax is not able to read values from CGI2 as it polls to get updated values after every 1 sec. It is able to get last value.
In some cases it is able to get 1-2 other values but not EVERY TIME.

Logically my program is fine. I have tested running CGI2 separately, it works fine. I have tested Ajax, and no issues with it as well. The status which it receives is 0 or sometimes 500.
However, altogether, it is not working.

Possible cause:
-Environment issue
-Running 2 CGIs simultaneously
-System() command used in CGI2 is not the right way to get output for Ajax

Any suggestion/solution would be really appreciable.

Thanks
