This implies that the page was already in write-back, even after we waited for a lock on the request. Sounds like some sort of race.... -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Will discuss upstream. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So I'll assume it is FIXED. Please reopen if the bug recurs.
