I have 5Gb. Maxima eats up the memory very fast; so if you use a
ulimit you need to set it high enough, or to look quick, if you want
to have a chance to see the maxima process before it gets killed by
the system because it has reached the memory limit. Here is the test I
used:
ulimit -v 2500000
make truc; sleep 1; ps auxww | grep maxima; killall maxima
