However the metadata service works fine. Tried to replicate the metadata server with just the linklocal port info alone modified and still observe the issue. Please find the linklocal info and the tcpdump outputs below. root@server9:~# curl -s http://10.87.118.173:8085/Snh_LinkLocalServiceInfo? | xmllint --format - <?xml version="1.0"?> <?xml-stylesheet
