[hobbit] Question about using no-cache on rrd for xymon 4.3.0.0.beta-2

[Stewart, Tom L.]

Yes, we are still seeing holes of NO update (blank spot) even after 24
hours. We don't have that many systems (a few hundred) and the problem
is very random across different systems at different times.

The more poignant question is, are you still seeing the update lags? 
And are the timestamps on the actual RRD files changing (not the rrd
channel control files, as you show)?  The option does exist in
xymon-4.3.0-beta2 source.
