[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

Any idea ?

Thanks
