How to run soffice.bin in headless mode on a IPV6 machine

Hi, I have been running soffice.bin in headless mode on a IPV4 machine using -

./soffice “–accept=socket,host=“172..18.*”,port=8000,tcpNoDelay=1;urp;StarOffice.ServiceManager” --headless --nofirststartwizard --norestore --nocrashreport --nologo &

But now I am switching to IPV6 and ran the above script to run the LIBO, Now this process stopped somewhere on the way and never completed. It kept the CPU 100% busy all the time. The startup doesn’t happen and port in never listened.

whats the problem? What am I doing wrong? Is there any change with the script for IPV6, Do you even support IPV6?
