Alternatively, you have insufficient memory to load your program.
Alternatively, the run-time system could not find enough file handles to open and, therefore, load the code.
Resolution:
Either the library that contained the program has been canceled, or the program is no longer available on the program search path. Ensure that the program is available either on disk or on an open library.
Either free some memory or restructure your application so that it uses less memory.
Increase your operating system file handles limit.
