Hi Frank and all list members:

I have a problem with Table. 
The agent would be coredump sometime when the manager walk a large Table.(6Col*600row)

void equipmentTableEntry::update(Request* req)
{

  if (currentRequest == req->get_request_id()) return;
  currentRequest = req->get_request_id();

  start_synch();
	int PerformanceStatus=1,CollectInterval=15,EquipmentStatus=1;
    if(collectInterval::instance)
    collectInterval::instance->get_value(CollectInterval);
	time_t now;
	time(&now);
	if( now get_value(PerformanceStatus);
    if(equipmentStatus::instance)
    equipmentStatus::instance->get_value(EquipmentStatus);

	clear();
	if(PerformanceStatus==1 && EquipmentStatus==1)
	{
    char buf[1024];
	struct tm* dt;
	MibTableRow* r;

	now -= now%(CollectInterval*60);

	for(int i=0;itm_year+1900,dt->tm_mon+1,dt->tm_mday,dt->tm_hour,dt->tm_min);
	r = add_row(buf);
	r->get_nth(0)->replace_value(new SnmpInt32(rand()));
	r->get_nth(1)->replace_value(new SnmpInt32(rand()));
	r->get_nth(2)->replace_value(new SnmpInt32(rand()));
	r->get_nth(3)->replace_value(new SnmpInt32(rand()));
	r->get_nth(4)->replace_value(new SnmpInt32(rand()));
	r->get_nth(5)->replace_value(new OctetStr(buf));

	now -=CollectInterval*60;
	}
	}
	else
		lasttime = 0;
  end_synch();

  
}


Any suggestions would be greatly appreciated.
Daniel
