Sorry, it seems I used these parameter without care. I guess I only need to set physical memory limit, a.k.a. resident memory. OT: I don't know why I have max locked memory (kbytes, -l) 32 But it has been like that before I set ulimit. > What I do is use /etc/sercurity/limits.conf (from pam_limits) with a > couple of entries like those: > | @users hard nproc 1000 > | mb hard nproc 5000 > | @users hard as 2097152 > | mb hard as 6291456 > | mb hard nice -5 > | mb hard rtprio 5 > Meaning, everyone but me (mb) may use up to 1000 processes per login, > with a max. address space of 2 GiB each; for myself the limit is 6 GiB > and 5k processes.

I don't have a file called /etc/sercurity/limits.conf and neither can I find information about it by using 'man limits.conf'. Further I couldn't find a package called pam_limits to emerge. Can you give me some clue which package I should emerge in order to set limits.conf ? Thank you very much for prompt help!
