Sep 12 12:09:54 Kitchen-iBook WindowServer[693]: Reserved range exhausted. (0xbbf98000 to 0xbc021000 goes out of bounds)

What does this mean? I know the WindowServer handles application windows and is a parent process to all user apps. But what am I to make of this, if anything?

The window system tries to keep window buffers and hardware in a reserved address range. When a request is made for a new window, and it won't fit in that address range, the message is logged once. On the version you are running, when an allocation succeeds, the message logging is re-enabled, and when a buffer cannot be allocated in the reserved range, the message is logged again.


When buffers cannot be allocated in the reserved range, they are allocated starting at the lowest free memory address that will hold them. There are a few software tools that, when accounting for memory use, assume that all memory in that reserved range is window storage. The message simply indicates that the combination of hardware and window buffers in use needs to use storage outside the reserved range.
