RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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 Brian Smith 2022-04-01 13:29:39 UTC
Description of problem:
On RHEL 8.6 beta, with tlog session recording enabled, I am seeing the following problems:

- Ansible consistently hangs on "gathering facts"
- SSH connections to run commands intermittently hang until input is provided


Version-Release number of selected component (if applicable):
tlog-12-1.el8.x86_64

How reproducible:
Every time

Steps to Reproduce:
1.  Setup RHEL 8.6 beta system
2.  Enable tlog session recording for all users (I did this from Cockpit)
3.  Create a test user account
4.  Setup SSH keys so this test user account can SSH to the localhost with key authentication
5.  Run the following command:

while true; do ssh localhost date; done


Actual results:
With session recording disabled, this command will continuously run and show the  date.

With session recording enabled, this command will randomly hang until you press "enter".  Once you press "enter", the command will keep running and then randomly hang again.


Expected results:
Session recording should not cause this command to randomly hang until input is provided


Additional info:
This is affecting Ansible "gather facts" as well which causes the playbook to hang.
