That error message occurs if the Unix pipe() function fails.
According to the man page, it can fail because:

- Too many descriptors are active.
- The system file table is full.
- The fildes buffer is in an invalid area of the process's address space.

The last one is highly unlikely, so my best guess is that you are
running an app (probably not OzTeX) that is using a lot of system
resources.  Try quitting all other apps and run pdflatex again.
If that fails, I guess you'll have to log out and back in.
