autobuild[sn-devel-184]: intermittent test failure detected

[autobuild]

The autobuild test system (on sn-devel-184) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

   https://git.samba.org/autobuild.flakey.sn-devel-184/2019-03-27-0944/flakey.log

The failure seems to be in the "ctdb" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-184/2019-03-27-0944/ctdb.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-184/2019-03-27-0944/ctdb.stdout
  
The top commit at the time of the failure was:

    lib: Make fd_load work for non-regular files
    
    Follow-up to
    
    https://lists.samba.org/archive/samba/2018-September/217992.html
    
    and following. This also fixes a small and very theoretical race: Between the
    fstat and the read call the file size might change. This would make us fail on
    potentially legitimate files.
    
    This is more complex and probably slower, but looking at the use cases I don't
    think the speed matters.
