samba - Jul 2016 - ndr_pull_share_mode_lock failed: Buffer Size Error

Hi list,

I'm getting a lot of these on a CTDB cluster serving files to Windows 
clients:

Is this anything to be concerned about? It's pretty much the only thing 
in the logs...

nothing to worry about. We're still circulating patches that will get
you rid of the log spam:

<https://bugzilla.samba.org/show_bug.cgi?id=12005>
<https://lists.samba.org/archive/samba-technical/2016-July/114897.html>

Cheerio!
-slow

Many thanks Ralph, looking forward to that going into release.
