Are you doing some kind of recursion and getting stuck or overflowing the
stack?
If you create something like:
function Factorial($x)
{
if ($x == 1)
{
return $x;
}
else
{
return $x * Factorial($x-1);
}
}
You can get into a problem with overflowing the call stack with a
sufficiently high value for $x.
