Have app originally created in AAOD6, integrated with Tomcat6 running on VP. Upgraded app to AAOD7,
integrated with Tomcat 7 and still running on VP (also updated the runtimeconfig war and lib).
Upgraded script gets the StackUnsynchronized.

It means the somewhere in the app is not synched up due to the upgrade. Is the app using any modules? If so, have those modules been upgraded exported from the new environment? You may want to try re-generate the project and modules manually by using the right click menu option Orchestration Designer->Generate project.

Was thinking along those lines although the app does not call any modules.
I created a short script that sets a var and plays a phrase to determine if
it was app related and the test script fails the same way.

Is must be runtimeconfig but, I can't determine why from the catalina logs.

Are you running the app in the development environment or deployment? If deployment, have you upgraded the common runtime support library files?

Yes...updated runtime support libs.

Make sure you don't have two scertcommon<version>.jar files in the Tomcat/lib directory. Can you post the trace.log file for running the simple test app that you have trouble with?

No duplicates and no trace.log generated (tracing is enabled).

The vpAppLogClient.log has the following...don't know if it means anything.

These errors show when you access the app through the web browser.
Have tried making really calls? Do you have the following properties enabled so that trace log get generated?

data/ddrt.properties

localddtrace=enabled
localapptrace=enabled
showxml=enabled

Also can you post a screenshot of the validation screen of the web browser loading validate.jsp.

Verifying directly through Tomcat browser seems to be the problem.
If I go into VP WebAdmin and verify app there it works!

However, if I call the number assigned to the app the call drops
after a few seconds of silence. No app log generated...I'm looking
through the VP logs to see if they indicate why the call isn't answered
by the app.

Why can I verify in WebAdmin but, call doesn't work? The app server
with the app I'm testing is a new addition to this setup. There is also
an app server local on the VP. Apps on the local app server answer
calls when using the same phone number...

If the call reaches the app server, the app should generate some logs. When it works through EPM, do you see some logs?

Checked the call detail for test calls I made today and
app url is an old url...not the one in the application admin.

Attached are screen shots.

Thinking MPP restart is needed. ?

I don't quite understand this. It seems to me you have 2 applications configured with different IP. Is that right?

No...one application, PFirst_PmtsT administered on AEP with
url 10.0.99.38:8080/...

I place a test call and app doesn't answer so, I check logs
then reports. Can't find any info in logs but call detail report
shows system using a different url.

This app was previously using the 'different' url but, client added
an app server and I deployed app on it and changed url in WebAdmin.
But change does not work.

If I go into 'Applications' through WebAdmin I can verify url...I can
page through the app.

But, calling the AEP fails. Because of the url issue describe above
I'm assuming.
