AppleShare IP places its file memory cache in the Mac OS segment as listed in the About this Computer command under the Apple Menu. With Mac OS 8.0, the About this Computer allocation for Mac OS does not account for the cache AppleShare IP sets aside for its use. As a result, it appears a larger amount of memory is accessible in the Largest Unused Block than is actually available. The AppleShare IP file cache memory is in use, but is not accounted for in this window.
You need to adjust the cache allocated for other applications in the AppleShare IP Web & File Admin application. Open AppleShare IP Web & File Admin and choose Web & File Server Settings command under the Server menu. Select Cache from its pop-up menu and increase the memory allocated for other applications. Save the new cache setting before closing the window.
Note: This does not occur with Mac OS 7.6.x.
