I suspect it just got missed in the stack of emails.  Hopefully it will 
percolate to the top soon.

I did a search on the mailing list and found Charles posting with a 
patch for this dated back in Nov 2007. I made the change and 
recompiled and it fixed the problem.
 
The change to be made is still at line 177 of the do_ncv.c
 
Change from  "if (split_ncv && (paridx > 1)) {"
Change to  "if (split_ncv && (paridx > 0)) {"
 
 Does anyone know why the following changes didn't make it to the 
current versions of Xymon?
 
Thanks

Hi Henrik,

I tried to update my hobbitd_rrd to the current snapshot version, and I
got loads of "Duplicate DS name: lambda" when using split-ncv.

I found the error lies here :

                                create_and_update_rrd(hostname,
testname, params, NULL);
 
                                /* We've created one RRD, so reset the
                                 * params for the next one */

With this modification, it works.

Thanks for your great software ! I hope 4.3 will be out soon !
