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.

Comment 9 Leslie Satenstein 2018-03-27 03:26:52 UTC 
Here is a way to demonstrate a memory leak.

Begin your gome session.
Invoke "system" (a gnome utility) that shows memory use by application name.
focus on gnome-shell
On a fresh logon, the shell will show around 200megs consumed
invoke aisleriot  a few times and exit
Each time aisleriot is invoked, it consumes around 5 megs
On exit, the 5 megs do not appear returned to the shell.

More simpletest. 
invoke aisleriot and then firefox and then aisleriot
you will find that the gnome-shell memory use is monotonic increasing, even after quitting firefox and aisleriot

Other gnome programs cause a similar effect.

Programs that do not use gnome-shell (Dropbox), on exit, return all memory that was assigned.


Footnote.
Is the monotonic memory increase shown by gnome-shell due to the shell or to Aisleriot / firefox, both not releasing memory back to the system?
