The JVM (Java Virtual Machine) memory threshold is not user configurable. When either the cache poll routines run, the first test checks how much free memory that is available to the JVM of theDisclosure Management Web application. If the free memory is less than 1 MB, the least used taxonomies are automatically unloaded until the amount of available memory exceeds the threshold (1 MB). The least recently used taxonomies are determined by examining the time stamp of when a taxonomy was last used or accessed. The more amount of time that has elapsed since a taxonomy was last used, the greater the chance that it is unloaded. The most recently used taxonomies have the best chance to remain in memory.
