decaf.lang.Thread doesn't free memory when phtreads used
--------------------------------------------------------
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: Chris W.
Assignee: Timothy Bish
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 each 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.
