My agent terminates because status = -21

[Kjersti Grønnevik]

Hi

My agent terminates right after I have started it because the status = -21.
What can be possible causes and solutions to this?

Hope this is understandable and thanks so much for great help so far! 

Best regards, 
Kjersti 



Here is some of my code:

int main (int argc, char* argv[])
{
	if (argc>1)
		port = atoi(argv[1]);
	else
		port = 4700; //the 161 port is taken

	Log::initLog("snmp.log", "snmpagent", 15, 20000);

	int status;
	Snmpx snmp(status, port); // Here I get status = -21

	if (status == SNMP_CLASS_SUCCESS)
	{
		LOG_BEGIN(Log::INFO, LOC);
		LOG("main: SNMP listen port");
		LOG(port);
		LOG_END;
	}
	else {
		LOG_BEGIN(Log::ERROR, LOC);
		LOG("main: SNMP port init failed");
		LOG(status);
		LOG_END;
		exit(1);
	}
