Have you tried creating a reasonably small test-case that provokes the

IIRC, Roland said that the sequence of messages corresponded to a fork
immediately followed by another fork by the child. Perhaps something
simple like

  #include <unistd.h>
  int main(int argc, char **argv)
    if (!fork()) fork();


  #include <unistd.h>
  int main(int argc, char **argv)
    int i;
