【问题描述】：
我们使用 smack 库来建立到 GCM 的 XMPP 连接。我已经在应用程序上有很多连接，我们已经实现了 Smack 库的 ConnectionListener 类。所以我们使用下面的方法。
@Override
public void connectionClosedOnError(Exception e) {
logger.error(e, "connectionListener::connectionClosedOnError::appKey::{}::clientId::{}", appKey, clientId);
}
这个实现已经运行了很长时间。但是过去 2 天我们收到了这样的错误；
05:16:50,846 ERROR [CcsClient ] -

这是什么原因？
