在Tomcat服务器农场中使用Log4j2运行Java WebApp的过时文件处理问题的问题

发布于 2025-01-28 19:28:26 字数 7011 浏览 2 评论 0原文

我们有一个Java Spring Web应用程序，其log4j2配置了使用RollingFile Active在Tomcat Server Farm上运行，并配置了NFS存储。

catalina out log正在编写大量执行 java.io.io.ioexception：Ompolete File Hander 显然是在Log4j滚动文件时（压缩日志文件，生成新日志），

让我们说我们有应用程序.log带有描述符521的log，这是文件描述符所有农场的服务器。 weberver1.com正在用app.log编写，并检测其必须进行文件滚动，压缩日志并生成新的app.log，这一次其文件描述符为853。所有其他WebServer.com在文件中都有描述符521且未能写入日志文件并产生异常。

log4j2中是否有任何选项将app.log文件空的而不是创建新的文件，以便app.log mantains始终是同一文件描述符？还是其他建议？

谢谢。

编辑：Catalina日志的确切错误是

We have a Java Spring web application with Log4j2 configured with RollingFile active running on a Tomcat server farm with NFS storage configured.

Catalina out log is writing a lot of execptions java.io.IOException: Obsolete file handle apparently when Log4j is rolling the file (compressing the log file an generating a new log)

Let´s say we have app.log with descriptor 521 and this is the file descriptor all the servers of the farm has. webserver1.com is writing in app.log and detects it has to do a file rolling, compress the log and generates a new app.log and this time its file descriptor is 853. All the other webserver.com has during a time the file descriptor 521 and fails to write to the log file and produces the exception.

Is there any option in log4j2 that empty the app.log file instead of creating a new one so the app.log mantains always the same file descriptor? Or any other suggestions?

Thanks.

Edited: The exact error from catalina logs is this
