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.

Description Ivan Necas 2017-03-07 08:20:49 UTC 
It's easy to write a template that would read from STDIN, e.g. following snippet hidden in a longer template

<pre>
grep something
</pre>

would cause indefinite job. The job can be cancelled but the eats resources by sending live updates while it does nothing. We should redirect STDIN to /dev/null when we run the script so such calls would end up with error.

Upstream bug assigned to mhulan
Comment 6 Adam Ruzicka 2017-08-02 13:26:02 UTC 
Verified.
Satellite-6.3 Snap 9
Package versions:
satellite-6.3.0-16.0.beta.el7sat.noarch
tfm-rubygem-foreman_remote_execution-1.3.3-1.fm1_15.el7sat.noarch

1) Run "grep something" on a host
2) The job starts
3) The job ends with exit code 1 because grep could find something in empty input
