This is a known issue, bug 520, and is already being worked on:
    http://bugzilla.xorp.org/bugzilla/show_bug.cgi?id=560

In the meantime:
* Can you post the log message(s) and XORP configuration which are failing?
* Which kernel version and Linux distro are you using?
* Which protocol(s) are you attempting to run?

I can readily reproduce the condition when attempting to run PIM with 
the rtrmgr/config/multicast4.boot sample config, on FreeBSD 7.0-RELEASE, 
where one interface is not connected to a switch.
