I'm running tomcat9 under Ubuntu 22.04 with an haproxy 2.8 in front of it.
I'm wondering about the following in the logs:

File /var/lib/tomcat9/conf/tomcat-users.xml is definitely there.
It occurs every 10 seconds.
Don't know who is causing this and why. Permissions? Ownership wrong?
-rw-r----- 1 root root 2756 Jan 15 2022 tomcat-users.xml
Believe the ownership was wrong. Maybe it came from migrating an old
installation.
What are the correct perms/ownership in /var/lib/tomcat9 and below?
What is the user-owner of the JVM process?
Check that all of the above would be both readable and executable by
that user:
ls -ld /var
ls -ld /var/lib
ls -ld /var/lib/tomcat9
ls -ld /var/lib/tomcat9/conf
... and of course that the JVM user can read
/var/lib/tomcat9/conf/tomcat-users.xml which I assume is true since you
said you already checked it.
What is the cwd of the JVM process?
The first message ("reloading") has the full path, and the second
message ("file not found") only mentions a relative path. I wonder if
that is the difference.
