[logback-user] RollingFileAppender with SizeBasedTriggeringPolicy keeps writing to rotated file

22 May 2013

      Hi I have an RollingFileAppender with a triggering policy of rotating by
size when the log reaches 32MB and a maxIndex of 1, configuration below.
It happens that after rotation logback keeps writing to both files. Is this
expected? My understanding from documentation is that it will stop writing
to the current log, rename it and starts writing a to a new file with the
name of the File parameter.

I'd appreciate your clarification if I'm not understanding well the
RollingFileAppender and SizeBasedTriggering behavior.

Thanks,
Rolando
