Run compilebench on the mountpoint, for example:

./compilebench -D /mnt/replicate/ -i 25 -r 75

Do some graph changes repeatedly on the servers


for i in `seq 10`; do gluster volume set quick-read on; gluster volume set quick-read off; done

glusterfs client crashes. And on the subsequent mounts, mkdir and rmdir crashes the client.
