Hello Don.
I had similar behavior, although not as dramatic, before installing FixPack1 and bunch of associated APARs. Of course, I was on AIX with 7.1.3. You don't mention the version or platform. Prior to 7.1.3 on AIX - I also had similar behavior. I avoided 7.1.2 for some of these symptoms.
We also had the situation where unmanaging a subnet for the frame interfaces on a router would unmanage the entire router and hub router. The opposite was also true; managing the frame interface network subnet would manage the router and the frame hub router. This was due the design of our maps. Locations with their routers, switches and servers could be 2 - 3 levels below the top level (home) U.S. map.
Two more ideas you probably have already considered:
    Have you checked ovwdb cache and current database object count?
    Is the router ICMP or SNMP status polled? I've seen the router object act unusual with SNMP status poll and long response times.
Hope this helps.
Let us know what you find.

Subject: [nv-l] Bizarre Router Behavior

I have discovered a Cisco 2600 router on my network that NetView is having a problem with.
The router has three interfaces (loopback, Frame and Ethernet) and thus, three networks attached.
All is drawn correctly.  However, when I Manage/Unmanage the router it has NO affect on the interfaces.
When the router symbol is unmanaged, the underlying interface symbols remain green.

When I manage/unmanage the interfaces, the router changes from green to blue as expected.

Status Source is Compoung-Propagated
Resolutiuon is ok.
nmdemandpoll output is exactly the same as another "normal" router.
Object information also appears to be normal

Has anyone seen this behavior before?  What could be the cause?
