I set the reporting to DEBUG and the log files show:

First of all, I don't have the solution for you.
However, I had the exact same problem a couple of days ago and from what I can tell:
1. It thinks there is another poller running (duh ofc...)
2. This happens when you fiddle around with the poller settings web page ie enabling/disabling the poller, switching between spine and cmd.php etc.

I would advise you to disable the poller, reboot the server or restart relevant services (mainly mysqld), wait a while (more than one poller cycle) and enable the poller again.
Sorry for the voodoo style troubleshooting advice but those are some of the actions I did and somehow it fixed itself.
I think there are many severe issues in this area and I'm still having problems myself :(
