                    --< XLIB error message >--

  program spec :

     everytime,       

     X_CreateGC - X_ChangeGC - X_PolyText8 - X_FreeGC 

  1. this program executed.   -------  non-problem.                    
  2. suddenly output XLIB-error messages to disply.  ----  what's happened ?


   Output Message :

3371.1	Ran out of resource IDs	LOWELL::KLEIN		`Fri Sep 28 1990 14:23`	12
	You ran out of resource ID numbers. Each client is assigned a limited range of ID numbers and the current implementation of XLIB does not recycle them when the corresponding resources are freed. If you are interested, I can post code that allows you to re-use resource IDs with some small changes to the application. Another approach is to cache resources (GCs, etc) yourself rather than destroying and recreating them. This second approach is not always so easy but may result in more efficient code (less work for the server to do, but possibly more for the client). -steve-
