This is an odd resource problem. Maybe memory related? It looks like you
have already opened the file descriptor and are unable to read it. If it
were a  problem with  file descriptors  I would  expect to  see resource
errors when trying to  open() them. But here you already  have an fd and
cannot read() it.

This isn't  likely a  kernel limit  but rather a  user limit.  What does
ulimit report?
