   - It's hard to tell because we have `logAbanded` enabled, but I don't see anything in the `tomcat7` service logs in the systemd journal
 - I sent another mail to the dspace-tech mailing list with my observations
 
+- I spent some time trying to test and debug the Tomcat connection pool's settings, but for some reason our logs are either messed up or no connections are actually getting abandoned
+- I compiled this [TomcatJdbcConnectionTest](https://github.com/gnosly/TomcatJdbcConnectionTest) and created a bunch of database connections and waited a few minutes but they never got abandoned until I created over `maxActive` (75), after which almost all were purged at once
+  - So perhaps our settings are not working right, but at least I know the logging works now...
