We had many devices not set to the correct location due to https://jira.observium.org/browse/OBS-2767
Updated to r9505 and after doing so we reset the geo location via web interface (device properties -> Geolocation -> Reset GEO location)
On any device that this was done to it seems like they do not exist to the poller any longer, none have been polled since the above action was taken. I based this info from the Per Device stats in the Pollerlog section (all of the devices that had their geo location reset were last polled 5+ hours ago, everything else that was not touched are being polled as expected every 5 minutes)
I see these errors in the db.log file, they appear to have shown up when the Reset GEO location operation was done on each device:
