Log4j in clustered environment

由 Deadly 提交于 2019-12-23 05:02:02
问题 I am using log4j for a web application running in clustered environment. Under few circumstances the logging is lost for some of the processes (not particular). I am not able to pin point why.

EDIT : Following is log4j XML along with AsyncAppender that I am planning to use <?xml version="1.0" encoding=
