Hi, I tried type "ulimit -Hm 4250" in my bash, in order to limit the RSS of all the proccesses forked by the bash to 4250 KB. However, when I did a "make" the my bash, the "pstree" showed "bash---make---sh---sh---make---g++---cc1plus", the RSS of "cc1plus" can still be over 20MB. (And later I tried "ulimit -Hm 2", still no effect at all) I am using linux-2.4.18. Shall I try other kernel versions? and which ones?
