Hi, BTW, in the catalina.out log file, I do see these lines:
01-Apr-2020 01:53:17.775 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Dfile.encoding=UTF-8 01-Apr-2020 01:53:17.775 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Xms4096m 01-Apr-2020 01:53:17.775 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Xmx4096m 01-Apr-2020 01:53:17.775 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -XX:NewSize=256m 01-Apr-2020 01:53:17.775 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -XX:MaxNewSize=256m So from that logging, it seems like Tomcat IS seeing those parameters, so why does it not seem to be using the larger amounts of memory?
