  ERROR CODE:  F

  MESSAGE TEXT:  unresolved contention for VSI Fortran RTL global
  resource

  EXPLANATION:  Failed to acquire a VSI Fortran RTL global
  resource for a reentrant routine.  For a multithreaded program, the
  requested global resource is held by a different thread in your
  program.  For a program using asynchronous handlers, the requested
  global resource is held by the calling part of the program (such as
  the main program) and your asynchronous handler attempted to
  acquire the same global resource.

  This error is not returned by IOSTAT.
