Error description

  • When fork needs 64K pinned pages, the page size management
    daemon is asychronously woken to create more 64K pages if
    possible so as to increase the amount of 64K pinnable frames.
    In some of these cases, fork() will fail instead of retrying to
    give the daemon more time to complete.
