Description Jan Hutař 2017-04-04 20:14:12 UTC
Description of problem:
With 20k hosts registered, concurrent registration of more than 30 hosts is almost impossible due to big ruby memory consumption.


Version-Release number of selected component (if applicable):
satellite-6.2.8-4.0.el7sat.noarch


How reproducible:
1 of 1


Steps to Reproduce:
1. When there is a small number of hosts registered to Satellite and with
   some tunings, it is possible to concurrently register almost 100 hosts
2. With 20k hosts already registered, Satellite had a severe memory issues
   when I was registering 36 hosts in parallel


Actual results:
Ruby RSS memory goes up to 68 GB


Expected results:
It should be possible to register more systems in parallel than 36 no matter how many systems is already registered

Are these 20k active hosts or just the host entries?

This is scale environment with containers ( as same as real hosts).
