Subject: Can't start webrick as the root user

Hi,

I am trying to start Webrick as root user and get TCP Bind error even
though the port appears to be not taken.  Running the same script as a
non-root user that owns the ruby installs works just fine.

1) Running dvdelta_start.sh runs just fine as a non root user
2) Running the same script gives me TCP Bind error
 su - dvdelta -c "/opt/apps/datavail/current-delta/dvdelta_start.sh
start" 2>&1 >>/tmp/dvdelta.log

I'd appreciate any pointers to help debug this issue.

Thanks.

Prakash
