Ted, Thanks for your quick reply. With the newest rc8-based snapshots I am no longer getting segfaults, unless you wanted me to roll back to the rc6-based snapshots to reproduce the segfaults. Per your latest request I disabled delalloc, and voila, no more data corruption! Then I enabled delalloc and disabled mballoc and file corruption to /lib/rc/init.d/nettree returned. So delalloc is the culprit. I hope this will help figure this out.
