I have 4 active maps, total number of nodes is 879.
123Switches - 426 nodes - all except 8 are NINKs
cp-core - 373 nodes - all except 7 are NINKs
123interconnects - 19 nodes
iWan - 61 nodes

Strange error whereby I have no errors on maps until I added cp-core. All maps were showing clear, and all nodes in 123Switches.conf were displaying without error in the poller. When I add a the cp-core map, all maps show errors. If I remove cp-core again the other map's errors clear.

I assume it is to do with load, so upped the poller threads per process from 1 to 3, but no effect. Do I need to beef up the machine it runs on? It's a VM with one vCPU and 2GB of RAM running RHEL5 and Cacti 0.8.8b with Weathermap 0.98

Who is your polling times? Are you having poller overruns (when the poller takes longer than the interval to run)?

POller is 1 minute. I'll bet you're right. Will adjust to 5 and see
