[jira] [Commented] (LOG4J2-2681) SocketAppender in UDP mode can't split messages

    [ https://issues.apache.org/jira/browse/LOG4J2-2681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16917625#comment-16917625 ] 

Andreas Mager commented on LOG4J2-2681:
---------------------------------------

The network traffic in UDP and TCP is the same.  rsyslog changes the behavior of handling the log message in the different Protocolls.
In UDP new lines will be replaced by #012. In TCP new lines generate a new log record.
