Ok Amar, I have a HUGE problem with 2.0.8

I have a client up and everything is fine UNTIL I try to write a specific file (a backup of a client vol) when I try to write both replicate servers that host that file immediately crash.
Here is the client log:

Here is both server's output from the very handy trace command you gave me
