e2defrag has a setting to allocate buffers. According to the number i gave
it, it should have allocated 128MB .. this is in accordance to what i
observed in ps aux during the runtime. All vmstat data i had was in buffer
and lost when later i ran the graphviz programs and deadlocked the computer.
I was not expecting to reboot. I can always try it again. e2defrag didn't
deadlock the computer, but it did cause that unusual behavior that i observed
just before deadlocking it with graphviz. What kind of vmstat output do you
want, every 10 seconds?
