Log4J too many files

Hi I am using Log4j.
I have created one utility class which I use in other classes to get the logger.
public class CommonLogger {



private static Logger logur;



private TimeLogger() {

}



private static Logger Logur(String className) {

Configuration configur = null;



//default values for logging

String pattern = null, logFile = null, level = null;



try {

configur = new PropertiesConfiguration("/WEB-INF/Time.properties");

pattern = configur.getString("Log4j.pattern");

logFile = configur.getString("Log4J.path.logFile");

level = configur.getString("Log4J.level").toUpperCase();

logur = Logger.getLogger(className);

PatternLayout patternLayout = new PatternLayout(pattern);

FileAppender appender = null;

try {

appender = new FileAppender(patternLayout, logFile, true);

} catch (IOException ioe) {

System.out.println("Exception in class="+ className+" method="+"Logur"

+ " " + ioe.getMessage());

}

logur.addAppender(appender);



if ("INFO".equals(level))

logur.setLevel((Level) Level.INFO);

else if ("DEBUG".equals(level))

logur.setLevel((Level) Level.DEBUG);

else if ("ERROR".equals(level))

logur.setLevel((Level) Level.ERROR);

else if ("FATAL".equals(level))

logur.setLevel((Level) Level.FATAL);

else if ("TRACE".equals(level))

logur.setLevel((Level) Level.TRACE);

else if ("WARN".equals(level))

logur.setLevel((Level) Level.WARN);

else

logur.setLevel((Level) Level.INFO);



} catch (ConfigurationException ce) {

System.out.println("ConfigurationException in class=" + className+" method="

+ "Logur. " + ce.getMessage());

}

return logur;

}



public static Logger getLogger(String className) {

logur = Logur(className);

return logur;

}







}


I use this class in other classes to get logger like,
Logger logger = CommonLogger.getLogger(SomeDao.class.getName());

Its opening too many file descriptors and giving me the message too many files open.

I dont know how to limit number of open file descriptors.
What mistake am i doing
Any light on this?
Thanks in advance.
