EDI commserver can not find port 6900 error message

We receive the errors when we run the ED501 job.  and causes the below errors

We are on current version of EDI in 9.0.1 and run on a AIX platform
There were changes in the the /etc/netsvc.conf file
from host= bind4, local
to     host= local, bind4 
We believed this caused this not to work. 

Has anyone experianced this type of issue. 
Any suggestions how to eliminate this issue.
