Hi All, I'm running 4 Intel(R) Xeon(R) CPU 5160 @ 3.00GHz with 12GB of memory (fat supermicro) / 2.6.20-1.2952.fc6 and have a few statistical user who gobble all the memory with no limits set. Is using this conf ( /etc/security/limits.conf ) the right / best place to start limiting? Is the setting of this reset on boot or is there a command/etc to set on the fly? I hope this is _not_ off subject, thanks much, Gary
