如图，第一次登录进来经常会出现KSQL错误，但是重新登录或者刷新什么的就不会再出现。

看下后台报错是什么？？
第一次失败问题，有可能是数据库连接断开了

Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 62,697,390 milliseconds ago.  The last packet sent successfully to the server was 62,697,391 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

日志中有这一个关于MySql的内容，是否还是按上面的处理方案？
