Thanks all. Just for the record, it passed test008 with th following
configuration
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 524288
stack(kbytes) 32768
memory(kbytes) 32768
coredump(blocks) 2097151
nofiles(descriptors) 2000
That is, the only element I changed was data(kbytes) from 131072 to 524288
