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 Chad Truhn 2011-02-28 16:06:05 UTC 
Description of problem:

Upon locking and unlocking the terminal gnome-screensaver uses ~9.3MiB of memory.  


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

# rpm -qa | grep screensa
gnome-screensaver-2.28.3-8.el6.i686


How reproducible:

Always

Steps to Reproduce:
1.  Log into machine
2.  Check memory usage of gnome-screensaver
3.  Lock screen
4.  Unlock screen
  
Actual results:

Memory used by gnome-screensaver goes up ~9MiB indefinitely 

Expected results:

May use more memory initially, but should release memory after a period of time

Additional info:

Similar to bug on Fedora 12
https://bugzilla.redhat.com/show_bug.cgi?id=533614
However, this does not seem to have a cap.  My system is currently using 687.0MiB for gnome-screensaver.  That bug shows no resolution. 

Also found a similar bug reported against RHEL 5.4 saying that x11perf-umove but says it was fixed in RHEL 6.  Not sure if it is related, but probably worth mentioning.

I was able to re-create this issue on 3 different systems that I tried, all running RHEL6 workstation.  (We are currently "beta" testing RHEL 6.0 for replacement of machines at my company).
Comment 2 RHEL Program Management 2011-02-28 16:38:21 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.
Comment 3 Siddhesh Poyarekar 2011-03-30 12:01:09 UTC 
From a run of gnome-screensaver in valgrind:

==2443== 12,288,000 bytes in 1 blocks are possibly lost in loss record 4,070 of 4,070

==2443==    by 0x68D413: g_cclosure_marshal_VOID__VOID (in /lib/libgobject-2.0.so.0.2200.5)


So the real culprit is gnome-desktop. Reassigning to correct component.
Comment 4 Siddhesh Poyarekar 2011-03-30 12:04:32 UTC 
This has been fixed upstream with the following commit:

http://git.gnome.org/browse/gnome-desktop/commit/?id=af477956ddd06e3821bbcc3e9337a637fe91584a

Patch applies directly to RHEL-6 source.

The fix for this bug has been identified as the fix for rhbz#639732 also, FYI.
Comment 11 Tomáš Bžatek 2012-02-02 11:19:58 UTC 
Bug 639732 is going to be fixed in upcoming RHEL release, closing this one as a duplicate. The issue and the patch are practically equal.

FYI, since GnomeBG is used in several Gnome components, this might affect gnome-settings-daemon as well when nautilus is set not to draw the desktop.
