The other metrics ('traits') might also be problematic here. May be wise to disable the pool monitoring unless really used.

It should not be a trait, and probably should be only captured very infrequently. Reduce frequency by moving summary to detail for other pool data.

Description of problem: rhq/modules/plugins/jmx/src/main/resources/META-INF/rhq-plugin.xml <metric displayName="Heap Maximum Size" property="{HeapMemoryUsage.max}" displayType="summary" dataType="trait" description="Maximum amount of heap that can be used for memory management. This amount of memory is not guaranteed to be available if it is greater than the amount of committed memory. The Java virtual machine may fail to allocate memory even if the amount of used memory does not exceed this maximum size." units="bytes"/> Although it is 'max', for PS Eden size, there is a new value every time this metric is collected. It should not be a trait, and probably should be only captured very infrequently. This ends up creating thousands of database records for every JVM instance. Work-around is to disable this.
