Get "Assertion failed" in ConnectionMonitor.cpp, with Ice-3.0.1-VC80

jingkewhu

I get a problem in my VC++ code:

"Assertion failed!
File: .\ConnectionMonitor.cpp
Line: 65
Expression: !_instance
version: Ice-3.0.1-VC80
platform: Win XP SP2
compile: VS 2005

code:
I want to test how many clients can my server support,

In the class VDClient
=======
bool VDClient::InitClient(string strMac, string strServerIP, string strPort =

"10040", string strTimeout = "5000")
{
try
{
int argc = 0;
//Ice::InitializationData initData;
Ice::PropertiesPtr properties = Ice::createProperties();

//
// Set a default value for "Hello.Proxy" so that the demo will
// run without a configuration file.
//
m_strMac = strMac;
string strVDSrvProxy = "VDSrvCtrl:tcp -h ";
strVDSrvProxy += strServerIP;
strVDSrvProxy += " -p " + strPort;
strVDSrvProxy += " -t " + strTimeout;


properties->setProperty("VDSrv.Proxy", strVDSrvProxy);
properties->setProperty("Client.Endpoionts", "tcp");
//initData.properties->setProperty("Ice.ThreadPool.Client.Size",

"5");
//initData.properties->setProperty("Ice.ThreadPool.Client.SizeMax",

"10");

communicator = Ice::initializeWithProperties(argc, 0, properties);
VDPrx = VD::VDSrvPrx::checkedCast(communicator->stringToProxy

(properties->getProperty("VDSrv.Proxy")));

if(!VDPrx)
{
string err = "ErrorMessage";
GlobalFunc::instance()->PrintMessage(err);

return false;
}


std::string _uuid = IceUtil::generateUUID();
ident.name = _uuid;
ident.category = "";
clientAdapter = communicator->createObjectAdapter(properties-

>getProperty("Client"));

ptrVDClient = new VDClientProxyI();
clientAdapter->add(ptrVDClient, ident);
clientAdapter->activate();
VDPrx->ice_connection()->setAdapter(clientAdapter);

return true;
}
catch(const Ice::Exception& ex)
{
ostringstream ostr;
ostr << ex;
string s = ostr.str();
string err = "Error：" + s;
VDPrx = NULL;

GlobalFunc::instance()->PrintMessage(err);
return false;
}
catch (...)
{
VDPrx = NULL;
GlobalFunc::instance()->PrintMessage("Error");
return false;
}

}
=========


===========
for (int i = 0; i < MaxClientNum; i++)
{
VDClient* pVD = new VDClient();
pVD->InitClient("8888", "192.168.101.87", "10040", "5000");
DoSomething();
delete pVD;
pVD = NULL;
}
===========
when MaxClientNum is 1000 or larger, I get the above problem, how can i fix it,
Thanks!


VDSrv.ice
===========
#ifndef VD_ICE_PC
#define VD_ICE_PC

#include <Ice/Identity.ice>
#include <Ice/BuiltinSequences.ice>

module MapC
{
dictionary<string, string> Context;
};


module VD
{

interface VDSrv
{
MapC::Context RequestToServer();
void HeartBeatRegister(Ice::Identity ident);
};

};

#endif
================

VDClientProxy.ice
====================
#ifndef VDClient_ICE_PC
#define VDClient_ICE_PC

#include <Ice/Identity.ice>
#include <Ice/BuiltinSequences.ice>

module VDProxy
{

interface VDClientProxy
{
void SendMessage();
};

};

Hi,

We only provide free support on the forums for the latest Ice version. Could you upgrade to 3.2.1 and see if you still get this assert?

Thanks,

Cheers,
Benoit.
