Knowage 停止响应 [在 Apache Tomcat]
Knowage stops responding [on Apache Tomcat]
我正在使用 Knowage 并设置了数据源、许多参数化数据集和驾驶舱。
我有一份详细的报告，需要很多数据集。
驾驶舱开始冻结，我必须重新启动 Knowage 服务器才能让它响应。
我将报告分成不同的页面，这似乎有所帮助，因为它一次只加载部分数据。
但是现在我添加了另一个数据集[总共14个]并且服务器再次崩溃。
我正在通过 jmx 代理监视服务器以了解它挂起的原因，但利用率似乎还不错。
Tomcat 只是挂起，从不响应。
servlet 似乎已停止处理请求，但我在日志中没有看到任何看起来致命的错误。
堆利用率还不错，但看起来确实不正常。

我认为问题是由数据库连接限制和 server.xml 中的最大等待引起的。
我注意到 jndi 配置中的属性错误，并更新了它们。
还没有再次发生冻结。
