Please try to recycle app services along with rscd and then check how it goes if that helps.
Why do you think restarting the appserver and agent will help here?
Can you attach the content installer log – should be in /tmp.
Issue resolved now.
we have modified mentioned file with provided data.
1. map root user in export file
2. Added appserver installation path in /etc/init.d/rscd
yep. i don't think you need to do the path thing though.
do you have the rscd and appserver installed in different places (one of them as 'local') ?
Yes, we have installed appserver in different places.
