Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHSA-2015:1592 0 normal SHIPPED_LIVE Important: Red Hat Satellite 6.1.1 on RHEL 6 2015-08-12 09:04:35 UTC

Description Justin Sherrill 2014-07-18 00:45:48 UTC 
Description of problem:

currently if you install a satellite on systems with a large number of cpus (16, 32, etc..) the number of pulp workers is very large.  In reality we only need around 8 workers max.  So we should default the config file in /etc/defaults/ to 6 or 8 or the cpu count if its lower than 6 or 8

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  Install satellite 6
2.  Check the number of workers  ps aux | grep pulp_workers (then divide by 2)


Actual results:
Does not limit itself to any number.

Expected results:
For a large cpu system should limit itself to 6 or 8

Created redmine issue http://projects.theforeman.org/issues/8266 from this bug
Comment 3 Bryan Kearney 2015-02-21 03:02:32 UTC 
Moving to POST since upstream bug http://projects.theforeman.org/issues/8266 has been closed
Comment 6 Elyézer Rezende 2015-04-07 12:31:23 UTC 
Verified on Satellite-6.1.0-RHEL-7-20150406.0

Steps to verify:

1. Installed Satellite
2. Fetched the CPU number
3. Checked the number of pulp workers (decreased 1 because grep matches itself)


Machine 1
=========

# lscpu | grep '^CPU(s):'
CPU(s):                32

# expr $(ps aux | grep -E "reserved_resource_worker-" | wc -l) - 1
16


Machine 2
=========

# lscpu | grep '^CPU(s):'
CPU(s):                24

# expr $(ps aux | grep -E "reserved_resource_worker-" | wc -l) - 1
16


To get the real number of pulp workers, the number should be divided by 2 as stated in the bug description, in both cases was 8.
Comment 7 Bryan Kearney 2015-08-11 13:34:24 UTC 
This bug is slated to be released with Satellite 6.1.
