Avati spent some time with me yesterday going through two different cores. He says he has all the info he needs now.
Yes, it is very easy to reproduce. It takes about 15 minutes.

Dan,
Will investigate as soon as possible. Can you paste the back trace using gdb?
"gdb -c <path to core file> glusterfs" and then type "bt".
Is this problem easily reproducible?
