I don't think you should be able to get there with dirty > dirty_max_internal, but obviously (assuming what's on the stack is correct) you did. I stuck a DTRACE in there on the copy I'm running (which isn't in the copy I posted and sent to you) and am torture-testing to try to reproduce this, so far without success (or with the DTRACE firing.) -- You are receiving this mail because: You are the assignee for the bug.
