This machine has a Core 2 Duo processor (i. e. 2 cores). On my Pentium 4 + Hyperthreading Linux machine is only dies after about a minute with: terminate called after throwing an instance of 'activemq::exceptions::ActiveMQException' what(): Cannot assign requested address Aborted However, this is to be expected, since the program causes thousands of sockets to be created. This doesn't seem to be the reason it crashes on Windows though. The code: {code:none} #include #include #include #include #include int main(int argc, char* argv[]) { activemq::core::ActiveMQConnectionFactory connectionFactory("tcp://localhost:61613?wireFormat=stomp"); while(true) { cms::Connection* connection = connectionFactory.createConnection(); cms::Session* session = connection->createSession(cms::Session::AUTO_ACKNOWLEDGE); cms::Topic* topic = session->createTopic("topic"); cms::MessageProducer* producer = session->createProducer(topic); delete producer; delete topic; delete session; delete connection; } return 0; } {code} The stack trace when it crashes: > activemq-cppd.dll!activemq::io::BufferedInputStream::read() Line 79 + 0x12 bytes C++ activemq-cppd.dll!activemq::connector::stomp::StompCommandReader::readStompHeaderLine() Line 194 + 0x19 bytes C++ activemq-cppd.dll!activemq::connector::stomp::StompCommandReader::readStompCommandHeader(activemq::connector::stomp::StompFrame & frame={...}) Line 101 C++ activemq-cppd.dll!activemq::connector::stomp::StompCommandReader::readCommand() Line 59 C++ activemq-cppd.dll!activemq::transport::IOTransport::run() Line 166 + 0x19 bytes C++ activemq-cppd.dll!activemq::concurrent::Thread::runCallback(void * param=0x003ad328) Line 152 + 0x13 bytes C++ msvcr80d.dll!_callthreadstartex() Line 348 + 0xf bytes C msvcr80d.dll!_threadstartex(void * ptd=0x003adac0) Line 331 C kernel32.dll!7c80b683() [Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] The line in BufferedInputStream::read is: char returnValue = buffer[head++]; There is a local variable called bufferSize with a value of 1024. However, the value of head is usually much larger than bufferSize (like more than 10000). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
