Interesting.... I am testing on ia64 so that does explain why I had not seen that particular failure. I am thinking this honestly sounds like a kernel bug, not a test bug. The test unmaps the page then calls mincore, it doesn't allocate any memory in between. It sounds like the munmap is not working in some cases. I may have to get my hands on a 32bit x86 system and see this for myself and try to understand what is happening. - Doug ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
