You said before that it was happening on a 32GB image - is it *only* happening on a 32GB or bigger VM, or is it just more likely? I think you also said you were using 1.7; have you tried an older version - i.e. is this a regression in 1.7 or don't we know? Dave -- Dr. David Alan Gilbert / dgilbert@redhat.com / Manchester, UK
