java - Does Weblogic interrupt long running threads -

i have mqevent listener thread continuously polls mq new messages , processes them. application deployed clustered weblogic environment. once application runs few months,the listener threads on of weblogic managed servers getting interrupted(at same time) resulting in listener being terminated. have redeploy application make work again.

i'm not able find interrupting thread. listener uses multiple

thread.sleep() calls i'm not sure how listener getting interrupted.

  public void run() {     while (!isinterrupted()) {      //keep processing messages , sleep      } } 

does weblogic interrupt long running threads , try shut them down?
