More specifically the following line also writes to /var/log/cloud.out ---------------------------------------------------------------------------------------------------------------------------------- (cd $CLOUD_COM_HOME/systemvm; nohup ./run.sh > /var/log/cloud/cloud.out 2>&1 & ) ---------------------------------------------------------------------------------------------------------------------------------- since run.sh calls _run.sh and both has "set -x" enabled, in certain situations they can keep logging messages to cloud.out without being aware of the settings in log4j-cloud.xml One way to fix that could be that run.sh and _run.sh would log to cloud.out only if a debug flag was set to true, otherwise only the java process would write to cloud.out and log4j would respect the settings in log4j-cloud.xml Thanks Saurav On Mon, Mar 17, 2014 at 8:47 PM, Saurav Lahiri <saurav.lah...@sungard.com>wrote: > Could it have something to do with the RollingFileAppender that is > being used. > The following > rollingfileappender<http://apache-logging.6191.n7.nabble.com/RollingFi > leAppender-not-working-consistently-td8582.html> link appears to be a bit > outdated but they more or less describe a similar problem that we are seeing? > > > On our environment that is what we have seeing for sometime on console > proxy.
