Unfortunately this is a known deadlock that can happen with swapping that there isn't an easy fix for. If you want a quick hack, try commenting out the 'wakeup(&proc0)' line in setrunnable(). It might take a bit longer for the kernel to swap processes back in but should avoid the deadlock. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
