One of our third party applications (SlickEdit) has been having its  
share of issues.  We finally had an error message (Xlib: resource ID  
allocation space exhausted) that produced an interesting Google hit:


Here is some of the relevant information from that page:

   The problem is that right now if you don't use the Display internals,
   and override the XID allocator associated with each Display  
   the code eventually hits this in libX11 (_XAllocID()):

     if (id != 0x10000000) {
         (void) fprintf(stderr, "Xlib: resource ID allocation space  
         id = 0x10000000;
         dpy->resource_id = id >> dpy->resource_shift;

   So, if you have an application running for weeks or months that
   allocates XIDs over a period of time, for GCs, Pixmaps, etc.
   you will eventually hit that, unless you carefully replace the core
   allocator for each Display, and reuse ids.

I can't vouch for the accuracy of that information, but it does seem  
plausible and applicable to my situation.  And it appears that this  
issue did not exist in CentOS 4, or at least I did not see it until I  
upgraded to CentOS 5.1.
