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();
};

};

#endif

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.
