Dale,
I have never used dbench before but I did the following:
/mnt/glusterfs $ sudo dbench -t 10 10 -c /usr/share/dbench/client_oplocks.txt
10 clients started
0 62477 6.35 MB/secc
Throughput 6.35386 MB/sec 10 procs
This was with patch 261. How does this compare to want you did? I was trying to reproduce your crash.
Harris
