-------------------------------
Summary: Memory leaks when using openwire with transactions (was: apollo becomes high heap memory.what wrong? )
> Memory leaks when using openwire with transactions
> --------------------------------------------------
>
> Key: APLO-342
> URL: https://issues.apache.org/jira/browse/APLO-342
> Project: ActiveMQ Apollo
> Issue Type: Question
> Components: apollo-broker, apollo-openwire
> Affects Versions: 1.6
> Reporter: tiansong xia
> Labels: test
> Attachments: apollo.xml, gcloh.txt

> The consumer consumes large quantities of messages by using transactional session.After consuming a lot of messages, java heap memory is high.But java heap memory becomes lower when i kill all the consumer's connection.
> Consumer code like this:
> Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
> MessageConsumer receiver = connection.createConsumer("test topic");
> receiver.setMessageListener(new MessageListener() {
> //DB operations
> session.commit();});
> apollo.xml:
> <queue id="com.zqgame.activeMQ.visitRecords" dlq="dlq.*" nak_limit="1" swap_range_size="2000" auto_delete_after="0" />
> <leveldb_store directory="${apollo.base}/data" read_threads="5" index_block_size="2048" index_cache_size="134217728" index_write_buffer_size="2097152" />
> <connector id="tcp-max" bind="tcp://0.0.0.0:61614" connection_limit="100" protocol="openwire" send_buffer_size="4096" receive_buffer_size="4096"/>
> About 30 connections(one consumer per one connection) consume 500-600 message per second.
> GC infomation:
> num #instances #bytes class name
