Thanks for the update Justin. My team tried to reproduce this manually but we were unable to.

Turns out I had I needed to change the script I use to copy previous install data. Due to a change in 19.3, the script was incorrectly updating data-server's folder.

Hi Tejas-

Sure thing. Let me know if you are looking for any other specifics.

Run 19.3 Linux installer
Copy data from previous 19.3 installation (K data, content, kafka logs, etc) - I will note I use a script I took from the docker tools to do this to avoid manual updates, though I can't see why this would matter.
Run configure script (I created a new repo from 19.3 for this and merged in my custom.properties to make sure appian-topology is still default
Start services, search, data-server, tomcat. Tomcat throws the error a few minutes into start up but will eventually start up correctly.

I reinstalled a few times just to re-trace my steps and had this same experience 3 times or so.

Hi Justin, what steps do you perform to reproduce this issue? I'd like to test this on my end to see if I am able to reproduce this as well.

It may be related to the ads-rts-linux component. On 19.2, I see that process listening on the 5450 port

But on 19.3 its on a different port
