Does anyone know of software to restrict clients to lets say 30% memory and 20% cpu stress? To prevent overload problems.

Oh, it's redhat btw.

Thanks.

There is a concept of login classes in BSD which does that.

In Linux I think the closest one can get to is
/etc/security/limits.conf

I hope this helps.
Have a great day

afaik you can do it with apache 2

Bump, anyone know how to do that with Apache? Installing FreeBSD and moving all virtual accounts is our last option..

We are experiencing quite some downtime due to overloads by scripts, mysql, etc, etc.

Thanks a lot.
