greedy Flume appender

[Martin Bobák]

Hello folks.

I'm using Tomcat 8.5.15 with log4j-2.8.2. I keep log4j2.xml [1] in
${catalina.home}/lib/. In this file I have several rolling file appenders
configured. Everything works fine until I add flume appender. All rolling
appender files have length 0 bytes and no data are written whatsoever after
adding flume appender. Will be glad for any help. Thanks.

Martin
