Author Limit resource usage per vhost

Hi all!

We have a problem on one of our webserver, one vhost hog all resources
spawning many httpd processes that raise the load average to 10 and
more!! So I'm looking for a solution, can someone suggest the right way ?

Thanks.
Regards, Davide.

You don't mention what version of apache you are running. FWIW, I'm
having similar problems and am currently looking at mod_bandwidth for
Apache 1 and mod_cband for Apache 2. I'm still doing some testing so I
can't make a recommendation at this time.

can you not use
RLimitCPU
RLimitMEM
RLimitNPROC
to set hard limits for the vhost thats causing the trouble?

I don't think those would work for me. They apply to processes forked
off from the apache child processes. Most of my sites are using
mod_perl and the request is handled within the apache child process.
