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

[Christophe Caron]

I don't think this application runs as a parallel application in thread 
mode. There is only one process (in thread mode, ps/top commande line 
display thread processes) which bypass the limits.conf configuration.

Normally the process shoud be killed if the memory limit will be reach ?

Thanks.
