------------------------------------

Sorry for getting back to you so late. I believe this issue was addressed in rc1 with LOG4J2-531. 
Does this issue still exist with rc2?

> Using sample config for RollingRandomAccessFile, with log name retrieved from enviroment variable "Fubar"...
> {code}
>     <RollingRandomAccessFile name="RollingRandomAccessFile" 
>         fileName="logs/${sys:Fubar}.log"
>         filePattern="logs/$${date:yyyy-MM-dd}/${sys:Fubar}-%d{MM-dd-yyyy}-%i.log.gz">
> {code}
> Along with a harness program,
> {code}
>     public static void main(String[] args) {
>         for (int i=0; i < 100000; i++) {
>             logger.info("Logger writes message for the nth time " + i);
>         }
>         System.out.println("Done");
>     }
> {code}
> If I use $\{sys:Fubar}, instead of, say a literal value, the contents of the first rolled file are lost. I had SizeBasedTriggeringPolicy set to 1 MB, meaning, 21296 log messages were lost.
