You should check two things:
1) are theses nodes in an unreachable area of your network ? if RFI is
enabled and the subnet or location where the node are located has been
detected as unreachable by netmon, the subnet/location will change to white
but the nodes inside will not change color as they are no longer polled.
The goal is to save some unnecessary polling as long as none of the router
is responding. To test that, do a quicktest on the node and it will tell
2) check how the nodes are being polled. There might be a conflict between
icmp/snmp reporting a different status.

I have two environments where I have problems with nodes staying green even
when they don't respond to ping from NetView (using the GUI to ping the
nodes, or using ping from the command line).
One environment (where I am able to test) is a VMWare-session which was
connected to a customer network. And even now, several months later, nodes
show up as green on the NetView map.
When I do Unmanage/Manage, they turn into 'unknown', but the other nodes
stay green (even across a reboot of the VM-session).
I have seen some indications of the same problem here, but not exactly the
