You're going to need to describe the issue in English and provide more details.

Calling client.writevalue() to write the signal point results in a significant increase in memory

[kevinherron]

You'll need to provide an example that demonstrates this.

Neither of the write examples demonstrate this and no other user has reported this.

public static void writeValue(UaClient client, String identifier, Object value) {
try {
LogUtil.writelog("=====写入【" + identifier + "】====开始", logName + "" + identifier);
//创建变量节点
NodeId nodeId = new NodeId(2, identifier);
//创建Variant对象和DataValue对象
Variant v = new Variant(value);
DataValue dataValue = new DataValue(v, null, null);
StatusCode statusCode = client.writeValue(nodeId, dataValue).get();
LogUtil.writelog("=====写入【" + identifier + "】====值：" + value + "【写入状态】：" + statusCode.isGood(), logName + "" + identifier);
Thread.sleep(500);
DataValue valueR = client.readValue(0.0, TimestampsToReturn.Both, nodeId).get();
LogUtil.writelog("=====写完读取【" + identifier + "】====值：" + valueR.getValue().getValue(), logName + "" + identifier);
if(valueR.getValue().getValue() != value){
StatusCode statusCodeN = client.writeValue(nodeId, dataValue).get();
LogUtil.writelog("=====重新写入【" + identifier + "】====值：" + value + "【写入状态】：" + statusCodeN.isGood(), logName + "" + identifier);
DataValue valueRR = client.readValue(0.0, TimestampsToReturn.Both, nodeId).get();
LogUtil.writelog("=====重新写完读取【" + identifier + "】====值：" + valueRR.getValue().getValue(), logName + "" + identifier);
}
LogUtil.writelog("=====写入【" + identifier + "】====结束", logName + "" + identifier);

    } catch (Exception e) {
        LogUtil.writeExceptionLog(e, logName + "_" + identifier);
    }
}

Must multithreading be used to call client read/write signal points？

[kevinherron]

Multithreading is not required.
