It seems we observed something similar in our cluster (20 nodes) when testing Bonnie in parallel ( using -s 5000, ie 5GB per node).
We have Opteron CPUs, do you also use opterons?

We are not 100% certain of this but think that very heavy reads/writes on a GFS mount elevate the load on the individual nodes considerably and result in crashing the entire (14-node) cluster. It appears that a shared PHP session ID directory is the primary cause of this.
Does anyone have any experience similar to this?
Thanks in advance, Duncan Morgan
