We recently ported our application from jboss-4.2.1 to  jboss-5.0.After the porting the our application log file stopped rolling  over I always overwrites TestServer.log but never creates  TestServer.log.1

I debugged the Apache Log4j and found that Log4j is actually trying  to rename the TestServer.log to TestServer.log.1 but the file is not  created in the folder. Once more thing that I observed was we have  log4j-1.2.8.jar included in our WEB-INF\lib folder, when I remove it  from our application the log file is rolling over properly. But I need  to place the log4j-1.2.8.jar in our application as we have various  deployment mode without application server.

We never had this issue in jboss-4.2.1, Please help me resolve this issue
