We are starting to experience that our poller is stopping.
We are seeing the following traceback and after that a few polls already initiated will follow but no new jobs will be started.
After this error, the discovery and the billing continues to run.
To get the poller running again we have to restart the librenms process.
I dont see any pattern in timing or specific devices being polled before the error is thrown.
The frequency of the error:
Oct 01 10:05:01
