Run a "/usr/OV/bin/mapadmin -l", how many maps are listed?
If more than one, have you made sure interface/node is unmanaged on all maps?
Are you doing this on the X11 GUI or the Web Console?

I have the exactly the same thing I unmanage an interface and the next
it alerts that it is down. I have even tried to allow only snmp and no
pings to it and this still is not helping.

A device, once unmanaged, will stay unmanaged.
That being said, there is one thing I can think of that will cause the
device to become managed again. The most common is that the
interface is a duplicate ip address of an interface on another
device. You actually have it figured out, you just dont know why;-)
What happens is when the other device is configuration polled, it
removes the interface from the first device and adds it to this device.
Then when the first device is configuration polled, it gets removed
from the other device and added back to the first one, except now
its managed. Any time a new interface is added to a device, it is
managed(unless otherwise configured in the snmp configuration).
So it looks like the interface simply remanages itself, but actually
that is not the case, it is removed, readded and managed because
it is newly discovered. SOOOO, now you what can you do.....well,
you can find the other device and reconfigure it. You should actually
be able to find in your trapd.log which other device the interface
in configured on, you should see a interface deleted on the other
device and then an interface added on the first one. It sounds
complicated, but we see it alot. Now, if you know this interface is
duplicated somewhere else for some reason in your environment,
you can simply define the interface as HSRP in the seedfile(%) and
then run "netmon -y". This will cause netmon to reread the seedfile
and set the interface as an HSRP interface, then you can unmanage
it safely and it should not return(at this point you can also hide it).
Hope that helps,
