(In reply to comment #1) > Please provide additional information on this issue. > Can you provide a small example which behaves like you describe? I'm using log4j on Oracle Application Server.and i'm configuring the log4j from a property file not on runtime, and am using category instead of logger. everything is working fine but suddenly all the logging activity hangs. to restore the logging activity i have to restart the OC4j. non from the applications deployed on the OC4J configure the log4j on runtime so it's configured only once on startup. i need to know what is causing this. ----------------------------------- example of loading the log4j: private org.apache.log4j.Category logger; logger = org.apache.log4j.Category.getInstance("ZainKSABilling"); ----------------------------------- does the deprecated method getinstance could have something to do with this issue?

Please provide the property file you use, and a thread dump (JVM and OS dependant) of OC4J of the situation where logging has stopped. My guess is that this is a resource deadlock. How many web applications do you run in OC4J?

I'll provide the thread dump as soon as the hanging starts
