Because the VM space was exhausted because the cleanup-on-close never
happened like it was supposed to...

And/or the VM space has to be contiguously allocated, and the necessary
memory could not be allocated after a couple of runs because it was
too fragmented.

You'll have to look carefully at the driver to see which is happening
(if either is the correct reason).
