As I already wrote in my previous comment, the first error
Errno::ENOMEM: Cannot allocate memory
means that your system is low of phisical memory.
The second one
Errno::EISDIR: Is a directory
means that the file is a directory; and that you cannot open a directory for writing, or create or remove hard links to it.
