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?
Created attachment 22212 [details] The log4j property file as soon as the hanging starts all the logging files defined in this property file stop being updated. there are 18 different application
I'll provide the thread dump as soon as the hanging starts
