I might have had a similair problem. haven't looked into it any deeper yet, but it looks like UDP NFS mounts with 16384 make the NFS server's kernel crash hard. after i found a workaround, i didn't have chance to trace this bug. My situation was that i was copying a bunch of stuff from a linux machine, which had options for nfs mounts set to 16384 byte blocks. When i set them to 8192, FreeBSD didn't crash any more. hope this helps... martijn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
