Apache Tomcat 10.1 无法删除临时文件

Question

我们刚刚将 Tomcat 从 9.0 升级到 10.1，将 Java 从 8 升级到 11。一切都运行良好，只是现在临时文件堆积在

Apache Software Foundation\Tomcat 10.1\work\Catalina\localhost\root

中。这会导致 Java 堆空间问题后出现 502 错误。我们看到这样的错误..

有什么想法可能是什么问题吗？

有时没有管理员权限我们无法删除C:盘的文件， 也许这些解决方案会对您有所帮助：

1. 使用管理权限运行您的 Java 应用程序。 （使用cmd）

2. 如果仍然遇到问题，请检查文件权限。确保 Java 进程具有删除文件所需的权限。
