DailyRollingFileAppender overwriting instead of rolling

[Matthieu Le Gall <ml...@techworks.ie>]

Hi,

I am having a problem with the DailyRollingFileAppender.
Some nights it rolls exactly as it should. Some nights, instead of
rolling and creating a new log file, it writes the current log in the previous log (overwriting the previous log file).
When it happens (and I couldn't figure out what event makes it happens), it always happens between two consecutive days.

A quick look at the log files dates shows the overwriting problem on the 2006-04-10:
[tmbb@twmbase ~]$ ls -l /home/mlegall/logs/WebApp*
7584   Apr  8 23:45 /home/mlegall/logs/WebApp.2006-04-08.log
7584   Apr  9 23:45 /home/mlegall/logs/WebApp.2006-04-09.log
129734 Apr 11 09:15 /home/mlegall/logs/WebApp.2006-04-10.log
24003  Apr 11 10:11 /home/mlegall/logs/WebApp
