Limits on memory usage
we have SL5.5 on our computing nodes.
Sometimes, users runs too many computations, and servers become unreachable due to lack of enough memory. I want to restrict total memory usage of users to a little bit lower value of physical memory, so under all circumstances the servers will have enough memory to run system services. I tried to limit several parameters in limits.conf file. But they didn't work. How can I limit total memory usage of users? |

PAM module pam_limits with configuration file /etc/security/limits.conf works for me. Limits are implemented per-login, not globally. |
I need global settings.
While I searching on google, I found something related with "cgroups". That may be a solution. |
