Bad file descriptor

[Anon]

I searched through the archive, there are similar questions, but I didn't have luck finding an answer.

Whenever I call fopen, file, readfile, or a filesystem function to open a http connection I receive that error:

$fp = fopen("http://example.com/");
Warning: Bad file descriptor on line X

Any ideas on how I can solve it?

and Line X is the $fp=blabla line?

yes, that's the conflictive line.
