Thank you for your inside.
my project using jdk 1.8 oracle 19c apache server weblogic 14c was spring 5.2 jsp 2.3
About 1000 users are using it at the same time. I set the heap memory to be very large. If I do not restart the server, the heap memory usage area gradually increases. After about 3 days, the heap memory usage rate rises to over 80%. The result of analyzing the heap dump with Eclipse mat It occupies a lot of heap memory in 'weblogic.application.metadatacache' and finalizer from java.net. My develop skills are limited in using this material. What should I suspect? The analysis results are attached.
Help me please.
