That certainly looks bad. Are you building OSCAR yourself, or is it
pre-built? I'm assuming that all local customizations are done using
separate config files or in the database, right? Can you get a fresh
copy of the oscar.war file?

That's nice and fast.

Strange that it's deploying, then undeploying, then deploying again. Is
it possible that there are weird file timestamps? Maybe something in the
future?
My guess is that the cp oscar.war /var/lib/tomcat9/webapps hadn't actually
finished yet when it tried to deploy it.
That can definitely break things. If you are going to drop a WAR file on
Tomcat, make sure that either Tomcat isn't running, or you are using the
Manager web application to upload-and-deploy the WAR file which protects
you from deploying mid-copy.
So the first 1.684ms attempt fails,
and then it tried again. (Times are UTC)

So the port is open, so I attempt to visit the /manage URL

And it just stalls.
Is there anything between Tomcat and your web browser? Like a reverse
proxy, firewall, etc.? What URL are you trying to hit?
I went to eat lunch and watch TV, so waited a few hours, and it's the same
afterwards. Note that it never told me that it had finished deploying this
war.
I've tried kill-3 repeatedly, on the main PID of the process, and gotten no
output.
Anything in the other log files?
Instead of kill -3, what if you use the "jstack" utility and provide the
PID of the running process? (You'll want to provide the PID of the
parent JVM process, not a specific thread.)
