> Key: AMQCPP-289
> URL: https://issues.apache.org/activemq/browse/AMQCPP-289
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Decaf
> Affects Versions: 3.1
> Environment: Linux Ubuntu 9.10
> Reporter: Christian Warmuth
> Assignee: Timothy Bish
> Fix For: 3.1.1
>
>
> If you run the following program:
> int main (int argc, char *argv[])
> {
>
> ConnectionFactory* connectionFactory;
> Connection *connection;
> activemq::library::ActiveMQCPP::initializeLibrary();
>
> std::string brokerURI =
> "tcp://127.1.0.1:61616"
> "?wireFormat=openwire";
>
> connectionFactory = ConnectionFactory::createCMSConnectionFactory(
> brokerURI );
> for (int i=0;i<1000;i++)
> {
> connection = connectionFactory->createConnection();
> connection->start();
> connection->stop();
> connection->close();
> delete connection;
> printf("Count %ld\r\n",i);
> }
>
> delete connectionFactory;
>
> activemq::library::ActiveMQCPP::shutdownLibrary();
> return 0;
> }
> the consumption of memory grows on every new connection, but the memory is
> never freed.
> After about 180 connections the maximum virtual memory (about 3GB on 32bit
> Linux) of the process is reached and its impossible
> to create a new thread for the client. I saw that the destructor of the
> Thread class is called, but the memory of the created threads
> is not freed.
> If I add the line:
> #ifdef HAVE_PTHREAD_H
> pthread_detach(properties->handle);
> #endif
> to the destructor of de decaf/ang/Thread class the memory is freed after
> destroying the connection.
> This is a quick and dirty fix, but I think somewhat is going wrong here.
