Jboss + MariaDB + Hibernate-IJ000453：无法获得Java的托管连接：/ UnicaPlatformDS

Question

嗨，我遇到了Jboss + MariaDB + Hibernate堆栈的问题，其他数据库工作正常。 在运行应用程序一段时间后出现错误

05/28/2019 10:25:07 WARN  util.JDBCExceptionReporter [233] - SQL Error: 0, SQLState: null

05/28/2019 10:25:07 ERROR util.JDBCExceptionReporter [234] - javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/MyDS

以下是我的standalone.xml数据源条目。

            </datasources>

我的尝试-

1-最小添加连接池。

2-等待超时，锁定等待超时和互动超时到最大值。

在我看来，这似乎是jboss或MariaDB的配置问题。

请帮助解决此问题。
