Description

The current MaxFileSize for RollingFileAppender is set to 4MB. This is too low for most production deployments. Very frequently we handle support cases for people where the logs have long since rolled over and finding out what happened just an hour ago requires digging through old log files (if they even exist because MaxBackupIndex=9).

I propose the MaxFileSize be set to 64MB and MaxBackupIndex=5 to have max log size bounded to 320MB.
