654 httpd!?!? That's helpful to look at...

Thanks. Here's the main culprits, before any attempt to change conf files. There's some name truncation. 654 httpd 259 neutron-server 257 nova-api 129 swift-proxy-ser 129 nova-conductor 129 neutron-metadat 129 glance-registry

Thanks, I had that info previously. Yes, I was able to reduce Nova-related service processes somewhat by changing 128 in the conf file to 4. But not all services seemed to obey the hint, and some of them I have no idea where the configuration is really done. Seems like much of this stuff wants to configure by CPU nodes available and/or GB RAM available... Is there a reasonable strategy behind this?

Have installed ocata using packstack --allinone. The beam.smp process running as rabbitmq eats up 25GB of RAM on a 1TB RAM system, with nothing configured except for defaults. /bin/nproc reports 128. I have another question concerning the ocata install adding thousands of processes to my otherwise unused system. Maybe these are related?

Installed using packstack --allinone. On large machine, nproc==128, mem=1024GB. Not all services can be trimmed down using conf files. Why have 520 processes for Nova as default? This is Ocata under CentOS.
