Jboss logging issue

Question

Our application is deployed on JBoss As 4.0x and we face some issues with JBoss logging. Whenever the server is restarted, JBoss stops logging, and there is no update in server.log. After that it is not updating the log file. Then we do touch cmd on log4j.xml, so that it creates the log files again. Please help me in fixing the issue we cant do touch everytime. We face this issue in both the nodes.

I could not figure where the problem is? If any other issues, we can check the log files. If log itself is not getting updated/logged, how can we move further in analyzing the issues without the recent/updated logs?
