[jira] [Created] (AMQCPP-654) memory leak
lx created AMQCPP-654:
-------------------------
Summary: memory leak
Key: AMQCPP-654
URL: https://issues.apache.org/jira/browse/AMQCPP-654
Project: ActiveMQ C++ Client
Issue Type: Bug
Components: CMS Impl
Affects Versions: 3.9.5
Environment: centos 6.9 based pod in k8s, cms version is 3.9.5, use std=c++11 in g++
Reporter: lx
Assignee: Timothy A. Bish
I use cms to receive and send messages to artemis, and the consumer has a memory leak. My code like this
{code:c++}
void MyConsumer::WorkThread() {
try {
{
std::lock_guard<std::mutex> lock(mtx_);
if (inited_) {
LOG<<"inted\n";
return;
}
if (SetMqClientId() != 0) {
throw std::runtime_error("init mq client id failed");
}
std::shared_ptr<cms::ConnectionFactory> connectionFactory(new ActiveMQConnectionFactory(conf_.broker_uri));
if (!connectionFactory) {
throw std::runtime_error("connectionFactory is nullptr");
}
connection = connectionFactory->createConnection(conf_.user_name, conf_.password, mq_client_id_);
if (!connection) {
throw std::runtime_error("connection is nullptr");
}
if (conf_.auto_ack) {
session = connection->createSession(Session::AUTO_ACKNOWLEDGE);
} else {
session = connection->createSession(Session::CLIENT_ACKNOWLEDGE);
}
if (!session) {
throw std::runtime_error("session is nullptr");
}
if (conf_.use_topic) {
destination = session->createTopic(conf_.dest_uri);
} else {
throw std::invalid_argument("error");
}
if (!destination) {
throw std::runtime_error("destination is nullptr");
}
consumer = session->createConsumer(destination);
if (!consumer) {
throw std::runtime_error("consumer is nullptr");
}
producer_ = new MyProducer(response_uri_, connection, conf_);
producer_->Init();
connection->start();
inited_ = true;
}
while (thread_running_) {
Message* mq_message = consumer->receive(check_message_interval_);
if (mq_message && thread_running_) {
onMessage(mq_message);
}
if (mq_message) {
delete mq_message;
mq_message = nullptr;
}
}
}
catch (const decaf::lang::Exception& e) {
LOG<<"error:"<<e.what()<<"\n";
}
catch (const cms::CMSException& e) {
LOG<<"error:"<<e.what()<<"\n";
}
catch (const std::exception& e) {
LOG<<"error:"<<e.what()<<"\n";
}
LOG<<"stopped\n";
if (thread_running_) {
sleep(restart_interval_);
std::thread tmp(&MyConsumer::Start, this);
tmp.detach();
}
}
{code}
The memory leak occurred even if I remove the onMessage method(the while loop does nothing)
