It appears that XORP is configured to use only the interface with
physical index 21, but the fatal error message was about an
interface with physical index 17:

[ 2006/07/17 16:01:32  FATAL xorp_fea:14932 FEA +298 netlink_socket_utils.cc nlm_get_to_fte_cfg ] Could not find interface corresponding to index 17

I guess this has been triggered by some route being added to the
kernel (or by internal route manipulations by the kernel itself).

To find the real reason for the failure, could you run the following
command in parallel with XORP:
"ip monitor all"
Try to point the entry that is printed right before the FEA crashes.

In addition, after the crash there should be a coredump file.
Please send the backtrace for that file, and some of the values:

gdb xorp_fea -c your_corefile
bt
frame 3		# Try a different number to get into
                # NlmUtils::nlm_get_to_fte_cfg()
