No heat map the first time?

[bortzmeyer]

I try to draw a heatmap. I get some warning and I don't know if they are serious or not:

% atlas-heatmap -t d.nic.fr -k MYKEY -n 1000
2018-01-26 09:28:32,590: Target: d.nic.fr
2018-01-26 09:28:32,590: Forming probes list

Then, the only produced file is a d.nic.fr_atlas_tools.png which is just a map, without measurement results on it.

I have to launch the command again with -m to get a result.

This time, I get a proper map.

In some other cases, I don't have the warning, but I still need to re-run the command to get a proper map:

% atlas-heatmap -t g.ext.nic.fr -k MYKEY -n 3000            
2018-01-26 09:36:52,327: Target: g.ext.nic.fr

I cannot reproduce this problem. Probably it is fixed in the new release. Could you please check if it still persists?
