No, that is not a significant part.
This is just a new process starting and doing a "let me close
every file descriptor they passed me" function.
It actually closes only 3 and 4 as the others are not
opened (closing them fails because they are simply not open).

Your problem is somewhere else.
Try to see what happens before the access denied message.
