我有一个运行Stratos 1.5.1的实例。在stratos过夜而没有与之交互之后，我在登录Identity Server时收到以下消息
我在url调用和user-mgt.xml的属性标记中都添加了autoReconnect为true
如果有人知道为什么autoReconnect不起作用会很好。感谢。

答案 0 :(得分：1)
我按照
的说明进行操作http://www.lahiru.org/2010/07/keep-live-connection-in-wso2-products.html
纠正这个问题。
这说明要保持mysql连接可用。这要求我添加这些属性
wait_timeout=259200
interactive_timeout=259200
和/etc/my.conf文件的值。我重新启动，然后等待24小时验证并再次尝试登录，这次它起作用了。
