Thread, state isDaemon()

Question

In a thread I have a run() method worked as follow:
    MyThread t= new MyThread();
    t.start();
    public class MyThread extends Thread {
        private boolean execute= true;
        public MyThread() {
        public void run() {
            while(execute) {
                while(execute) {
                    Thread.currentThread().sleep(5000);
    }After one or two days, sometimes thread go to the state isAlive()=false without generating errors, and the execution end without any reason.
If I try to install again Thread in this way,
    t= new MyThread();
    t.start();thread does not star again.
How can I solve this problem? have you ever had a similar experience?
thanks for help, regards, Denis.
