I've got exactly the same behavior
- red cross next to the stats service in the admin webinterface
- 'zmcontrol status' tells that every service is running
- graphs are not updated
after my upgrade from 4.5.6 build 1044 Ubuntu6 on Ubuntu Server 7.04 (feisty) to 4.5.7 build 1319 Ubuntu6.
I realized that the stats are still gathered. I ran a 'zmgengraphs' and the graphs were updated with reasonable values.
I tried to manually start (or stop, then start) 'zmstatsctl' without success.
Any solutions in the meantime?
