/bin/cat: Argument list too long

I'm encountering the following problem and not sure whether the problem lies in "cat or "bash" or "apache".

When the script is called from apache httpd cgi, it encountered ...

        /bin/cat: Argument list too long

The script has very huge usage of enviroment variables (more than 10k bytes). If I define fewer variables, it ran find under cgi.

If I ran under bash shell prompt, there's no problem even with longer string of variables defined.

Somehow running under apache, there's less memory left for running shell command.

The "cat" command is simply ...

        cat <<EOF
        some text less than 2kBytes

I've tried increasing memory size and stack size using ulimit before starting apache, but still encountering the same problem.

Any help is very much appreciated.
