autobuild[sn-devel-144]: intermittent test failure detected

[autobuild]

The autobuild test system (on sn-devel-144) 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-144/2018-10-06-1833/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-144/2018-10-06-1833/ctdb.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-10-06-1833/ctdb.stdout
  
The top commit at the time of the failure was:

    ctdbd_conn: Generalise inaccurate error message
    
    Seeing:
    
      ctdb_read_packet failed: Cannot allocate memory
      [...,  0] ../source3/lib/ctdbd_conn.c:121(cluster_fatal)
      cluster fatal event: ctdbd died
    
    The error is due to a memory allocation failure rather than ctdbd
    dying.  However, the error message makes people wonder why ctdbd died.
    
    Another alternative would be to wrap cluster_fatal() and have the
    wrapper interpret the return value from ctdb_read_packet() to choose
    from a set of more precise messages to pass to cluster_fatal().  For a
    memory allocation it isn't strictly necessary to call cluster_fatal(),
    but all is probably lost and it is still probably better to try to
    exit cleanly as soon as possible instead of crashing somewhere.
