It's definately happening still, sorry. :-( I recompiled a 100% static kernel and have had three more explosions, usually after starting exmh. (exmh takes 10 to 15MB of ram on this system due to my mailbox folder sizes). > But, keep a watch on it.

The SMP box that is doing fine is a P6, an NFS client and server (loading nfs.ko, it fsck's fast, so I use that box for making sure the modules work). The one that is crashing, is a P5, an NFS client and server (static kernel), and with a MFS /tmp. Both run softupdates (up to date src/contrib/sys). I suspect MFS is the key. There's the new VOP_FREEBLKS() stuff you added, and the corresponding calls to madvise to free the pages. Given madvise()'s murky history, I can't help but feel suspicious about it. I've unmounted /tmp and am about to thrash the machine. At the moment, it's sitting on: Swap: 120M Total, 376K Used, 120M Free Cheers, -Peter To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
