我有 Jersey 提供轻松的网络服务。客户端经常会中止通过 ajax 完成的请求，使用 ajax 中止方法，如下所述中止 ajax 请求 https://stackoverflow.com/questions/4551175/how-to-cancel-abort-jquery-ajax-request
在服务器端我得到以下输出。这不太好看到。有没有办法检测泽西岛中止的请求？
SEVERE: An I/O error has occurred while writing a response message entity to the container output stream.

中止的请求必须记录在 tomcat 访问日志中。您可以在其中找到所有请求和相关响应代码。
但您的问题可能与系统限制有关。在泽西岛，对于每个到服务器的请求，I/O 容器都会发送响应编写器的新实例
所以你应该检查操作系统限制位于等/安全/limits.conf。
提到的文件包含域、类型和值 fields.
域可以是用户名、组名或任何通配符。
类型字段可以有两个值（软或硬），soft为了执行软限制，hard用于执行硬限制。
值字段是域的定义限制:)
我想如果你增加tomcat用户的限制，问题就会解决。
tomcat 的示例配置
tomcat软nofile 102400
tomcat硬文件102400
tomcat软nproc 102400
tomcat硬nproc 102400
