We have done the NiFi upgradation from 1.18.0 to 1.19.1 and we also upgrade the java version from 8 to 11 and after upgradation we observe nifi using more memory than allocated and caching build in the nifi. we allocate memory to nifi as java.arg.2=-Xms1g and java.arg.3=-Xmx50g. we are using RAM-64 GB and Core-8 and the solid-state high-speed hard disk is 2T. OS is CentOS7.9, ARM64 hardware architecture. we uncomment the Garbage collector from bootstarp.conf but this is not useful for us. we keep the databasr repository, content repository, provenance repository, and flowfile repository in different disks.
