JBOSS版本：EAP 6.4.20.GA（AS 7.5.20.Final-redhat-1）
Java版本：jdk1.8.0_172-amd64
Red Hat：Red Hat Enterprise Linux Server版本6.10（圣地亚哥），64位
JBOSS配置为使用Kerberos身份验证连接到SQL Server，该方法可以正常工作，但有时会失去连接并且无法打开任何新文件，除非重新启动。重新启动后一切都很好。
用于连接到SQL Server的驱动程序是mssql-jdbc-6.4.0.jre8.jar
引发的错误是：

在错误堆栈的底部，您可以看到位于底部的GSSException异常。但是，这都是非常奇怪的，因为就在几分钟前它就可以工作。修复它的唯一方法是重新启动JBOSS。重新启动后，一切恢复正常。
有人遇到过类似问题，请分享您的知识以及如何解决？
在其他环境中完全相同的设置也可以正常工作。
谢谢！
