Widening the net a little bit to show all system calls that it is
doing may give a bit more of a hint. It looks to me that you should
be looking for fstatat64 system calls. Notice I added -F to the ls
options to force a stat of each directory entry. This is running on
bits a little newer than Solaris 11 Express.
