I used visualVM to analyse the garbage collection, which seems to be running around once every two minutes or so and taking around a second to complete. The JVM heap is around 60% of the max heap size. I have attached heap dumps from previous runs in earlier threads. I have taken a heap dump of the broker, still under load after 17hrs uptime, but the compressed file is too large to upload onto this forum. I checked the heapdump for LRUCache, but this has 9 live instances, unlike in the issue described in AMQ-3028. I will now bounce the server and turn on garbage collection logs as well.
