error on modelling

Hi guys,

another problem with zenoss modelling ( one of that is on http://www.zenoss.org/forum/1706#comment-5581 discussion ).

just on some devices, apparently identical we receive below error:

------------

sometimes repeated several times.
I'm not sure if it's related on collector issues BUT what I know is that even if I use our manager as collector we always receive same error...

BUT

if you try modelling another devices with just one digit of difference ( e.g. xx.xx.xx.23 instead if xx.xx.xx.24 ) all works fine. no errore and right model of device...

Even if I think that it's should be impossible I know that there is a reason...

Can anybody help me

thanks in advance
