When moving a device between pollers, errors may occur

In the event of a remote poller outage you may want to re-asign devices to another remote poller
while testing this scenario I found that cacti contiously tries to call back to the offline poller

Even if you disable the offline remote poller cacti still tries to call back to the poller
it would be better to have logic if the poller is disabled or in heartbeat status dont try to connect at all
A warning or notice should follow for admin they must resync the poller when it comes online to make sure the host table is up to date
