Log4j lose log information issue

[Cathie Lee]

I got problem of using DailyRollingFileAppender from Log4j. Our server is configured with two managed servers of WebLogic.

The problem is "we lost the log information in the rolled-over files at every mid-night." That means, I can see all the log info. in the file of "myerror.log" today, but in the file of "myerror.log.2004-12-02", there are only a few lines there. Attached please find the log4j configuration.

Is this related with our two managed servers, because managed servers tried to roll-over logs?

Can anyone explain how this rollover work? How it rollover logs for two managed servers?

Thanks,
Cathie
