Dear Monks

Sometime back, I had posted a query regarding Issue with executing long process through CGI and had asked for help.

I was clueless then as to why the browser was going blank or exiting with a success status immediately (without executing the exec command in the script!!!) but now I have figured out that the PATH env variable is the one that is causing the issue.

i.e. If $PATH is set properly, then the script executes the command and returns the results.

But, if $PATH is not correct, then the script sets

$data->[0] (line no 61)

and enters the loop

if (my $session = param('session')) (line no 7)

immediately and stalls (or exits )

I set some softlinks and then define the PATH during runtime for the script. Hence, this has become an issue if one of the links is not set properly.

Although I can somehow manage this issue by making sure that the proper links are set in the first place, I am curious as to why this is happening. Unfortunately, I don't know how to proceed further to find the rootcause of this problem.

Looking forward for some help to check this further
