I took a thread dump and it looks like there are a huge number of instances of org.apach.activemq.apollo.broker.PeriodStat which is causing the memory leak.
We are using JMS to send messages with a reply queue to receive a response. After each response we do close the Session and MessageConsumer. Any ideas what might be causing the issue ?
