[size=x-large]硬件配置：
8G内存，四核CPU
软件平台：
windows2003+Tomcat6.20+Birt2.5+S2SH
JVM内存设置：
-Xms1536m
-Xmx2020m
引起的操作：
一般的查询不会报错，当利用birt查询报表时就会溢出（只要一执行，数据库中没有几条数据）,两个项目中只有一个采用BIRT报表，另外一个应用就只是普通S2SH应用
birt获取数据采用:script脚本数据源：
获取数据：
[code="java"]
ft = new Packages.com.cargosys.birt.BirtFactory.getInstance();
delivers=ft.getDeliverView(params["startTime"].value,params["endTime"].value,params["code"]);
it=delivers.iterator();
return true;
[/code]
呈现数据：
[code="java"]
if(it.hasNext()==false){
return false;
}
var dmain=it.next();
row["mainId"]=dmain.getId();
row["mainCode"] = dmain.getCode();
row["createTime"] = dmain.getCreateTime();
row["carNumber"]= dmain.getCarNumberName();
row["sendFilialeName"]= dmain.getSendFilialeName();
row["receiveFilialeName"]= dmain.getReceiveFilialeName();
row["createUser"]=dmain.getCreateUserName();
row["driver"]= dmain.getDriver();
row["deliverCount"]=dmain.getTotalCount();
row["deliverWeight"]=dmain.getTotalWeight();
row["sosCar"]=dmain.getSosCar();
row["remark"]=dmain.getRemark();
return true;
[/code]
[/size]

单项目运行没有任何问题，数据量再大都不会出现溢出，添加多一个S2SH项目就会溢出，添加一个空的WEB应用，不会出现问题
