tiansong xia updated APLO-342:
------------------------------
Description:
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 after killed all consumer's connection.What's wrong?
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.
