NCV behaving badly

[Guðmundur Örn Ingvarsson]

Hi, I'm having some trouble with NCV after upgrading from Hobbit 4.2.0 to Xymon 4.2.3

Notably many of my NCV graphs are no longer updating, and these are the kind of errors I'm seeing in my rrd-status.log

2009-12-11 08:45:41 RRD error creating /usr/local/xymon/data/rrd/lia10bc01.li01r1d.lais.net/bladecenter.rrd: Duplicate DS name: tableborder

When the duplicate error is involved Xymon cannot create an RRD file, and the unknown error is when it can't update the RRD because it's parsing wrong from the HTML file.
For instance the TotalAllocatedPower variable it complains about is like this in the HTML

In the vase of the DS4800 the HTML code is like this.

I use = when I don't want NCV to parse and : when I want it to parse. Hence the commented lines in the html page.

Anyway, anyone know why NCV behaves so badly ?
