RE: slapd shutdown

I haven't yet applied the patches (due to constraints on when it is
acceptable to do such work within my environment) and I've just seen the
problem again.  As Howard said he had a 'suspicion' the patch for
ITS#4338 would fix this I take that as there is also a chance it won't,
so I thought it might be useful to share the additional logging output
I've captured this time...

Its also (perhaps) interesting to note that I'm only seeing this on one
of my openldap servers.  All my servers have identical configuration
except for the arrangement of which databases are masters and replicas
(each is a master for one database and a replica for others).  The one
expection to this is the server experiencing the problem which had a
syncrepl provider configured which my test server is currently a
consumer of.  Elsewhere I'm still using slurpd replication for reasons
outlined in ITS#4323.  I've just commented out this configuration in
case it is the cause. I'm not permitted to upgrade before tomorrow night
(unless this becomes so frequent that the risk of an upgrade it
outweighed by the problems caused - which isn't yet the case) so we
shall see if this happens again.

Heres the last few lines of log (not quite sure what is going on on
lines 3,4,5 looks like a logging bug perhaps?)....

Howard notes that the fix for ITS4338 may fix this issue, and has also 
updated the slapd_daemon code to report this condition under DEBUG_ANY 
rather than DEBUG_CONNS.  I'll have patches against 2.3.17 for both of 
these in a short while at my site
