Sql server Azure SQL Server出现ejabberd错误

我在Azure虚拟机Ubuntu14.04上运行ejabberd 16.06节点，并使用odbc实现大部分功能

问题是，几天后，ejabberd失去了与数据库的连接，似乎无法正确恢复，所以我必须手动重新启动ejabberd本身

错误：

2016-12-28 16:43:40.084 [error] <0.24869.2>@ejabberd_sql:check_error:1033 SQL query 'Q9525209' at {sql_queries,145} failed: <<"[FreeTDS][SQL Server]Communication link failure SQLSTATE$

如果您从配置中删除注释，它将被删除shorter@juergend完成：）badlop，ejabberd的主要维护者，刚刚在github上标记了这个问题
