最近在做一个项目，使用KEPServerEX 4.0 采集PLC数据，项目是JAVA写的，程序写好后，开始能正常运行
，采集数据和远程操作设备都正常，但是程序运行了大概两天左右后就报错了，采集和操作都不行了，报错
内容如下：

实在不知道原因，各位大神帮看看。
我连接OPC是通过utgard来连接的，代码如下：
ConnectionInformation connectionInfo = new ConnectionInformation();
connectionInfo.setHost("127.0.0.1");
connectionInfo.setClsid("6E6170F0-FF2D-11D2-8087-00105AA8F840");
connectionInfo.setUser("OPCUser");
connectionInfo.setDomain("");
connectionInfo.setPassword("123456");
ScheduledExecutorService executor = Executors.newSingleThreadScheduledExecutor();
Server mServer = new Server(connectionInfo, executor);
try {
mServer.connect();
Group group = mServer.addGroup();
//先通过OPC树形结构获取itemID
FlatBrowser browser = mServer.getFlatBrowser();
List<String> itemIdList = new ArrayList<>();
for (String name : browser.browse()) {
//匹配字符串获取想要的itemID
if (name.startsWith("STAND14.Device1") && !name.contains("STAND14.Device1._")) {
itemIdList.add(name);
}
}
int length = itemIdList.size();
Item[] itemArr = new Item[length];
for (int i = 0; i < length; i++) {
itemArr[i] = group.addItem(itemIdList.get(i));
}
//读取数据
Map<Item, ItemState> itemsMap = group.read(true, itemArr);
//入库省略
//关闭连接
mServer.disconnect();
}catch (Exception e){
e.printStackTrace();
}
