We found out that a fresh deploying of a FUEL controller node with CEPH onto a 24-Core machine with 32GB of memory resulted in a none working object storage. The issue was that the rados-gw service didn't came up "Operation not permitted".

The issue is that apache is too aggressively auto tuned by the script:
https://github.com/stackforge/fuel-library/blob/master/deployment/puppet/horizon/templates/zzz_performance_tuning.conf.erb

The number of servers and client are such high that we run out of different hard centos system limits (open files, max threads). Reducing the amount of start_servers made rados-gw service working.

Either introduce hard upper boundaries for such auto tuning or increase the system limits, too.
