> In my Tomcat startup, I have specified the log4j.xml file as -Dlog4j.configurationFile=<path
to file>
> It gets initialized properly as I see the logs coming in the app.log
> However, at midnight of each day when it is supposed to rollover, I see the following
directory structure
> {code}
> drwxr-xr-x 2 root root       62 Sep 18 00:00 2016-09
> -rw-r--r-- 1 root root        0 Sep 18 07:48 app.log-2016-09-18
> -rw-r--r-- 1 root root   351893 Sep 18 07:58 app.log
> {code}
> The file for the previous day gets truncated to 0 bytes and the directory 2016-09 contains
NOTHING. 
> I just want to log to app.log and each day, I want to save the previous days log file
as a .gz with the date pattern. But it is not happening.
> I was using log4j 1.x, I switched over to 2.x since I was having issues with log files
getting corrupted (log lines disappearing) when multiple tomcat processes tried to write into
the same file. 
> Please help me since these logs are critical to our application. Thanks.
