Ralph Goers commented on LOG4J2-3457:
-------------------------------------
I have got to be missing something as I don't see any code in
CustomMultiProcessRollingAppender that actually rolls the file. All I see is a
thread that deletes a file with a .roll extension after it was modified more
than 2 seconds previously. I am sure I could be of more help if I knew exactly
what was causing the rollover and how it works.

> In our application we require a rolling file appender which can be used
> across multiple processes targeting the same file.
> I wanted to check if current log4j1.x 2.17.2 bridge version supports multi
> process rolling file appender, if not then is there any plan to support this
> feature in future releases??
> For reference, as per our application requirement, I am attaching sample java
> class files for custom appender, custom multi process rolling appender,
> sample test program with multiple threads for which we can run multiple
> instances to test multi process rolling and log4j property
> file.[^CustomLogger.java][^JavaLoggingMultiThTest.java][^customlog.properties]
