Description David Gibson 2014-10-27 01:25:37 UTC
Created attachment 950873 [details]
Packet capture showing many DNS requests.

Description of problem:

While syncing content, satellite 6 often performs bursts of dozens of DNS lookups on its own IP within a second.  This is clearly wasteful.

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

pulp-server-2.4.1-0.7.beta.el7sat.noarch

(not sure what other package versions might be relevant)

How reproducible:

Steps to Reproduce:
1.  Subscribe to a number of repositories
2.  Set a number of repositories to synchronize content
3.  Observe packages coming from the satellite host.

Actual results:

Dozens of redundant self DNS lookups, being sent to the external nameserver.

Expected results:

Moderate number of DNS lookups, at most one every several seconds to minutes.

Additional info:

Attached packet capture shows the many lookups.  The satellite server is 192.168.17.20.

Since this issue was entered in Red Hat Bugzilla, the release flag has been
set to ? to ensure that it is properly evaluated for this release.

Comment 3 David Gibson 2014-10-27 04:04:14 UTC
Sat6 server is running on a RHEL7 VM if that makes any difference.

Comment 6 Bryan Kearney 2016-07-08 20:29:19 UTC
Per 6.3 planning, moving out non acked bugs to the backlog

Comment 8 Bryan Kearney 2017-01-13 19:41:05 UTC
This is an older bug which I do not envision being addressed in the near term. I am closing this out. If you believe doing so is an issue, please feel free to re-open and provide additional business information. Thank you.
