What language is it written in? If it's something like C or C++, for
instance the libraries open stdout/stderr by default. It might be
causing your problem - but I doubt it.

More likely is that you're getting an error during the execution and the
system is trying to write something to stderr (or stdout). For
instance, you might not have the correct permissions to execute the file.

Try this:

1. Log onto the command line interface (ssh/telnet)
2. su to the webserver user
3. cd to the directory you're PHP script is in
4. Enter the command just as it is in the exec() call.

What happens?
