On -stable I have managed (very easily) to get the CAM layer vs UMASS layer into a confused state where the CAM layer thinks it is still attached but the UMASS layer thinks it has detached / cleaned everything out. In both cases it appears that memory is being freed by one side which is still being used by the other side but I haven't tracked down the exact cause. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
