After finding out that ulimit -m no longer does anything on linux... I am now investigating the use of prlimit.

I have found that this is supposed to exists as part of util-linux / util-linux-ng, I have this installed on my system, however

find / -name prlimit

Yields zero results; I currently have installed

util-linux-ng.x86_64 0:2.17.2-12.7.el6_3

I have tried running

yum update util-linux-ng

Which brought me to version

2.17.2-12.18.0.1.el6

With still the same issue; I am running CenotOS 6.3, upgrading is not an option.

  • `prlimit` is only in [`util-linux 2.21`](http://karelzak.blogspot.de/2012/01/prlimit1.html), so it's not available for CentOS 6. – Sven May 02 '16 at 19:38
  • This page states `supported since Linux 2.6.36`, My current kernel is `2.6.39`, am I still missing something? – Matt Clark May 02 '16 at 20:02

Don't mix up a syscall with a user space command. prlimit(1) the user space program was added to util-linux 2.21 to make use of the prlimit(2) syscall available since Linux kernel 2.6.36. BTW, the default kernel on CentOS 6 is 2.6.32.
