It also liked to spontaneously reboot quite often. Disabling softupdates got rid of alot of the crashes, and the rest were due to SMP. SMP alone, and softupdate alone, and everything else, is broken on 4.0. I cvsup'd a few days ago, so it was a recent current. No, i am not going to try it again, this is a server, and i can't afford anymore downtime. Once i get another machine i can play on, i would love to move my 4.0-current source tree over, cvsup to update it, and make world to try it out and play some more. But its not possible right now. But then again, 3.4 with SMP + Softupdates is cause for trouble too and causes constant panics for me. Disable softupdates, and all is sweet again. I use softupdates on a non-smp system (also 3.4) and all is sweet aswell. So SMP+Softupdates on 3.4 is seriously broken. 3.4 + SMP + No Softupdates + Async is damn fast, and reliable. So thats what i use. martin. -- diskiller@cnbinc.com Linux/FreeBSD hacker Please use PGP: http://www.diskiller.net/pgp.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
