[Gluster-devel] glusterfs crash with mainline-2.5 patch 260 with dbench

[Dale Dude]

Harris,

I only ran 'dbench -t 10 10' without the -c. When not using the -c it 
uses all the test cases. Checking out 261 on this box and trying again. 
Ran 261 on another box with 3 parallel rsync's but the mount froze a few 
times and made rsync fail but mount became responsive after the timeout.
