Question

我最近在一所使用Tomcat和Railo的大学受聘。

在大多数情况下，Railo运行良好，但偶尔铁路冻结并停止渲染任何CFM或CFC页面，只是给出502错误。通常可以使用service railo_ctl restart解决此问题，但最近出现了更多错误：

此错误表示Tomcat进程本身已崩溃。该脚本尝试连接到tomcat关闭端口（通常是8005） - 但由于tomcat已崩溃，因此无法连接。因此，“连接被拒绝”错误。

对于PID文件，railo_ctl脚本只是检查位于PID文件中的进程ID。由于该进程已经死亡，因此PID文件不再相关，脚本会采取默认操作来处理它。

你真正需要做的是找出Tomcat崩溃的原因。检查catalina.out日志文件 - 因为它将是Tomcat崩溃原因的最佳线索。

希望这有帮助！

Railo和Tomcat冻结，PID未被删除
