Hello, I'm trying to upgrade to 7.3.0 but there seems to be a performance issue with the file watcher.
This is a test server so there is no traffic involved. The CPU usage is quite low but as soon as I create or modify a file under a folder monitored by CAS (e.g. `/etc/cas/config/`), the RAM usage dazzles and thus the GC is running and making the CPU usage exploding. The server is running through a sandboxed Systemd service but running it manually, with no Systemd invovled, creates the exact same issue. * Java : Adoptium Temurin 21.0.8+9 * OS : Debian 11 * CPU : 2 cores * Memory : 8 GB (with 6 dedicated to Java) First, I run the server (like this or manually, it's the same): $ sudo systemctl start tomcat-cas It looks like there needs to be at least a single sign-on for the issue to appear. Then, CPU usage is low: $ top -bn 20 -d 0.3 -p $(pidof java) | grep cas | tr -s ' ' | cut -d ' ' -f 10 | sort | uniq 0,0 3,2 3,3 Then I create a file in a monitored folder: $ touch /etc/cas/config/test Finally, CPU usage explodes: $ top -bn 20 -d 0.3 -p $(pidof java) | grep cas | tr -s ' ' | cut -d ' ' -f 10 | sort | uniq 106,7 154,8 193,3 196,7 200,0 After waiting for a few minutes, the logs have such error messages: Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "..." Here's the command used to start the server: $ java -jar -Xms3076m -Xmx6144m cas.war -Djava.net.preferIPv4Stack=true -Djava.util.logging.config.file=/etc/cas/config/logging.properties Here's what I've tested: - 7.2.7 with - Tomcat 10.11.14 - Spring Boot 3.4.4 - Issue present: No - 7.3.0 with - Tomcat 10.11.14 - Spring Boot 3.4.4 - Issue present: Yes - 7.3.0 with - Tomcat 11.0.11 - Spring Boot 3.5.6 - Issue present: Yes - 7.3.0 with - Tomcat 11.0.13 - Spring Boot 3.5.6 - Issue present: Yes Thanks for your time! -- - Website: https://apereo.github.io/cas - List Guidelines: https://goo.gl/1VRrw7 - Contributions: https://goo.gl/mh7qDG --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
