Thanks Imesh, Isuru, Amila and Martin.

As Martin mentioned, we had log enabled at DEBUG level.  This change will 
additional level of protection besides having good logging instrumentation in 
the code.   With the DailyRollingFileAppender, we can only hope that log file 
is rotated every 24 hr before the disk is filled up.

I've committed this change to both master and 4.0.0.  Please feel free to 
revert or make adjustment to the size/number of files if you think necessary.

Regards,
-Jeffrey

Subject: Re: Carbon log flooded causing disk full and reboot

Hi Jeffrey,

A great finding! Did this occur while running Stratos in single JVM mode 
without having any DEBUG level logs?
Please send these changes to both master and 4.0.0 branches.

Thanks

Hi,

In our Stratos deployment, we experienced issue where wso2carbon.log file grew 
as much as 13 GB causing disk full and instance reboot and Stratos 
inaccessible.   We're deploying Stratos using default profile.   To fix this 
issue, we modified log4j.properties with the changes listed below.

Please let me know if it's okay to push this changes upstream.   If so, which 
branch(es) should the changes be checked in?

Thanks,
-Jeffrey
