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 of problem:


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


How reproducible:
Occasionally

Steps to Reproduce:
1. set a memory threshold on dynflow executor (EXECUTOR_MEMORY_LIMIT=2gb in /etc/sysconfig/foreman-tasks in sat 6.3, /etc/sysconfig/dynflowd in 6.4

2. run some substantial load on the tasking system continuous resyncing and publishing of CVs might be a good start
3. wait for the memory limit of the dynflow process to cross the limit - watch production.log for 'Memory level exceeded' message

Actual results:
The process still keeps running, termination is not finished, the tasks are not proceeding anymore

Expected results:
The process exits in timely manner and new one gets started

Additional info:
I've written the reproduced based on customer observations, haven't reproducer it locally in production just yet, we however know about places where we wait in the termination phase without any timeout

Increasing the severity.
