Hi,
The OSPF process seems to have exited, typically the XORP processes will
print a message before exiting, it would be useful to see this message.
Could you run the router manager in the background and capture the
output, the following works for me with /bin/sh:
# ./xorp_rtrmgr -b ./ipv6ospf.boot > log 2>&1 &
If you are not already could you also try building from CVS so that you
have all of the fixes.
