this  is  a  page_fault  of the ifmon daemon. This will be started and
used once you perform 'monitor interface xx-x/x/x' maybe you have done
this  with  an atm interface. You should be able to reproduce this and
find  out what interface you start to monitor. I remember such kind of
errors  had  been  fixed  but you would need to contact jtac to confirm
based on the core file and the signature.

This has no operational forwarding impact apart form the monitor command.
