Timer is not working properly.After the completion of timer duration.. still its not coming out of the fork

OVM

Hi,

I wanted to run a timer for “X” duration . For this iam using the below code…

fork //{
	forever
	begin :label //{
			wait(flag==1);
          ovm_report_info(get_type_name,$psprintf("Timer is starting at3t...",$realtime));
        		#(X);
			expired=1;
			flag=0;
         end //}

		forever
		begin //{
			@(flag);
			if(flag==0)
                        disable label;
                end //}
 join //}

When i start the timer i will set flag to 1.And iam disabling the “label” thread only after flag becomes zero. That will be done only after expired bit become 1.

But in my condition, once after entering into fork ,Iam seeing the message statement “timer is starting at …” continuosly and after the completion of X duration also my expired bit is not going high.

Can you plz tell whats the problem with this piece of code.
