Abstract

LIC-OTHER-SRCB6005121-UNPRED IASP PAGE LEFT IN MEMORY DURING
VARY OFF

Error Description

There is a timing window between two tasks in the system, one  
is scanning memory looking for IASP pages to remove from        
memory, while the other is moving a page. If the page is moved  
from memory that has not yet been scanned to memory that        
already has been scanned, the page will remain in memory after  
the page removal process completes.
