Is it RELENG_4 (stable) or RELENG_4_5 (the security branch), and what was the build date? The reason I am asking is that there was a bug fixed sometime during the 4.5 cycle where a VM object could be freed while still holding pages undergoing I/O, resulting in this sort of panic. The fix is not a simple one-liner, however, so if this is what is causing your problem the best thing to do is probably to upgrade to the latest -stable. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
