Yep, indeed that instance segfaulted (for an older bug), while the other one went OOM. This diagnostic activity was thought for the OOM... > > What's the workload on these things?

To test hostfs I leaved in a infinite loop of "while :; do make -j3 O=<otherFs>; make clean O=<otherFs>; done" and variations, on the Linux kernel source tree. I also have heard of "ab", the apache benchmark, which could generate network load. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
