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.

Description amit yadav 2020-11-13 08:33:26 UTC
Description of problem:

Whenever I start the Xvnc service for any user, a process of vncsession also starts and goes into zombie state. If I stop the user's vnc service, the zombie process is also cleaned up.

Version-Release number of selected component (if applicable):
tigervnc-server-1.10.1-7.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Configure vnc service as per https://access.redhat.com/solutions/5544351
2. Start the vncserver service

Actual results:
vncsession process is going into Zombie state.

root       26082  0.0  0.0      0     0 ?        Z    09:38   0:00 [vncsession] <defunct>    


Expected results:
Additional vncsession process should not start and go into Zombie state.

Additional info:

This is not affecting the vncsession service. But it is causing confusion.
