OD 7.2.1 with Tomcat 8.5.23 and Java jre1.8.0_181

EP 7.0.2

Runtime platform: Tomcat 8.5.23 and Java jre1.8.0_192

Tomcat 8.5.23 in runtime fails calling a reuseable module with local invocation
Simolation is ok

Tomcat 8.0.53 in runtime is OK

Is Tomcat 8.5.x supported?

8.5.x is supported. You have to get some logs in order to figure out where exactly it fails.

Provided trace logs, Speech Projects and Screen dump from tests

I don't get this. You claimed you ran these on 2 different Tomcat versions. How come the url for calling the module in two different log files are the the same "http://aaepwebftest01.tdk.dk:8081/Aaod710Test01/Start"?

I guess its the port number 8081 that is making you confused

I have 2 Tomcat instans on the same server configured with same port number 8081

I started Tomcat 8.0 and made a test call and then stop the service

Then i started Tomcat 8.5 and made a test call

OK, that makes sense. It looks like the Tomcat 8.5 is not responding to the url "http://aaepwebftest01.tdk.dk:8081/Aaod710Test01/Start?___DDSESSIONID=0D22EBDCFEBA987B09DBBE36223572F4:/Aaod710Test00" for some reason.

Have you test the app Aaod710Test01 individually to see it is deployed OK on Tomcat 8.5 instance?

Just made a test to be sure, it works fine calling Aaod710Test01

I ran some tests on 8.5.23 but can't seem to reproduce the problem.

Did you test with my projects?

I found this in the release info 7.2.1 "connectionLinger"

Tomcat –
o On some versions of Tomcat you may encounter problems with Tomcat closing a socket too soon when it sends a redirect; specifically, if there are 2 redirects back to back without a VXML page being returned. To alleviate this, use the connectionLinger property in the connector configuration with a minimum value of 1. It is not known if this behavior is exhibited on other application servers.

Not sure if this cover this issue?

Yes, I tested your projects. They are pretty simple. This problem doesn't seem to be project related.
The information you found seems to make sense although I wasn't involved in it. You should give it a try.

Did you tests on a new instans of Tomcat 8.5.23 ?

Can you provide me som guidens of where/how to configure "connectionLinger".

I feel i have downloaded most of the internet without finding any useful.

I am not sure what you mean by new instance. It's 8.5.23. There is a newer release of 8.5 you can download from Tomcat website. You can try that.
Here is the Tomcat documentation where the connectionLinger attribute is mentioned:

https://tomcat.apache.org/tomcat-8.5-doc/config/http.html

I mean did you test with my projects on a new installed tomcat instance 8.5.23

I have already read the docs about connectionLinger, but I need an example how/where to configure this.

Yes.

This attribute would be applied like this in conf/server.xml

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000" connectionLinger=2
redirectPort="8443" />

You should try to look into some Tomcat logs like catalina.log and localhost_access.log to see if there is any indication of problem. I think this problem is related to the network.

Could you Zip the Tomcat folder 8.5.23 you tested and upload et to me, I will install it on my server and test.

Are you running on a 2008/2012/2016 windowsserver ?

My Windows server is 2008
