Hi,
I am using log4j for logging. I am working on a huge application and there would be
lots of logs each day. Thereby it is requried that the log files be stored and renamed
each day. The date is appended to the log file and that day's log file is stored. The
logs start writing afresh each day. The problem here is that at times the application
simply starts logging to the previous day's log file, for a while, and then starts
writing back to the current day's file again. I am not able to figure out what goes
wrong and when. The application is running on weblogic. Can anybody please help? The
log4j properties file is here....
