Description Radovan Drazny 2018-06-29 11:10:19 UTC
Description of problem:
When running a large number of remote execution tasks, a callback from smart proxy occasionally fails with the following error: 

2018-06-28T13:59:10 [I|app|f60e2] Processing by ForemanTasks::Api::TasksController#callback as */*

Version-Release number of selected component (if applicable):
Satellite 6.4 Snap 9

How reproducible:

Steps to Reproduce:
Run many ReX tasks in parallel. My scenario was running simple "date" command on 200 docker containers. 

Actual results:
"No SSL cert with CN supplied", task never marked as successful, even if it was successfully performed on a client.

Expected results:
No error, task is marked as successful.

Comment 1 Brad Buckingham 2018-06-29 15:09:25 UTC
Is this scenario with custom certs or the default certs?

Comment 2 Ivan Necas 2018-06-29 17:07:02 UTC
Additional question: was this one capsule setup, or more of them was involved in the process?

Comment 3 Radovan Drazny 2018-07-02 12:34:32 UTC
Standard install, default certs, just one satellite server and its integrated smartproxy.
