mule service start script raises exception with log file

I'm trying to rewrite the mule start script so it works as a service on a RHEL.

Currently I have it mostly done. It is starting and I have the most of the log files being successfully written where I want them. But there's a file named literally .log that I do not know what is for, neither where to configure (its name and path).

Such file is adding the following nasty lines in the mule_ee.log upon start up: 

log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: .log (Permission denied)

What is that .log file for? Where is the conf file to set it up to be written in a place where the mule user has permissions to write?

The .log file seems to be from the 00_mmc-agent app.

The problem therefore was in the log4j.properties file located in ./apps/00_mmc-agent/classes such file has the following appender configured: log4j.appender.file.File=${app.name}.log That ${app.name} variable seem to be not properly configured (not even in the default not modified mule starting script). hence the .log file name.

In ./apps/mmc/webapps/mmc/WEB-INF/classes/log4j.properties the appender is configured like this log4j.appender.R.File=${mule.home}/logs/mmc-console-app.log

So, to fix the startup error I modified the appender of the log4j.properties file located in ./apps/00_mmc-agent/classes to have this path:

log4j.appender.file.File=${mule.home}/logs/00_mmc-agent.log

It seems that log4j can't find that file because OS permissions. You can chmod to add permissions in your MULE_HOME dir. And also review your log4j config to see why is trying to read .log file.
