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-144/2018-07-19-0745/flakey.log

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

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-07-19-0745/samba.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-07-19-0745/samba.stdout
  
The top commit at the time of the failure was:

commit 359e52187fbc9b5f94570ff8d12607b4fc42e4f2

    ctdb-tests: Loosen match against pstree output in simple test
    
    As per previous commit, pstree can truncate output if it gets too
    wide.  Instead of matching against the script's full path and
    arguments, just match against the script name.
