[CentOS] /etc/security/limits.conf : rss

Hello,

I run CentOS 5.6 on a Dell PowerEdge R815 with 256 GB of RAM. We use Sun Grid Engine to schedule jobs on this node.

I want to limit the memory usage about 150 GB per process. So i use the /etc/security/limits.conf configuration file. I test this configuration with some tools with a lower GB limit (about 2 or 4 GB), and it works !

But, at least one process (oases - a bioinformatics tool) bypass this limitation and use always 240 GB of memory (the last run) !!

/etc/security/limits.conf ... # * hard rss 150000000 * soft rss 150000000 # * hard as 150000000 * soft as 150000000 # ...

# uname -r 2.6.18-238.9.1.el5.centos.plus

Any idea ?

Thanks
