Upgrade 10.2.04. to 11.2.0.1 autoconfig running longer on the database server

We have upgraded one of our 11.5.10.2 applications from database version 10.2.0.4 to 11.2.0.1 and so far all has gone well. I do find that running autoconfig on the database server side now runs much longer than it did under 10g. It has gone from 30 seconds to over 3 minutes in our split database configuration but does complete successfully. It does report two “WARNING: inbound connection timed out (ORA-3136)” in the alert log during the process and has the message below at the very end of the adconfig.log but again it does complete. This message is at the end
