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.

Red Hat Product Errata RHBA-2016:0761 0 normal SHIPPED_LIVE X.Org X11 server and drivers bug fix and enhancement update 2016-05-10 22:33:00 UTC

Description 马立克 2015-05-13 06:23:52 UTC 
Description of problem:
In the virtualization environment such as RHEV or oVirt, use the RHEL6 as the guest os of virtual machine. The vm use spice protocol. In the RHEL6 guest os, enable the gnome-screensaver and use the classic "floating feet" as screensaver theme. Use spice client connect to the vm, and login the desktop. Then don't log out, just close the spice client. As time goes on, the memory size which xorg process used will increase continually.

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


How reproducible:
Always

Steps to Reproduce:
1.Create a vm in the RHEV or oVirt environment, use spice protocol to connect the vm
2.Use spice client connect to the vm.
3.Install RHEL6.x in the vm(it should include desktop soteware package group and start up desktop as default)
4.Log in the desktop, make sure the screensaver has been enabled and the "floating feet" has been selected as the screensaver theme
5.Use top command to check the memory usage of xorg process
6.Don't log out the desktop, just close the spice client window
7.Several hours later, use spice client connect to the vm and log in with the same user.Use top command to check the memory usage of xorg process
8.Don't log out the desktop, just close the spice client window
9.More hours later, use spice client connect to the vm and log in with the same user.Use top command to check the memory usage of xorg process

Actual results:
As time goes on, the memory usage of xorg process will increase continually

Expected results:
the memory usage of xorg process should not increase to a very big size

Additional info:
If the user log out, the xorg process will be terminated. So after log out, memory leak can not be watched.
Comment 1 马立克 2015-05-13 06:27:00 UTC 
If use the VNC protocol, everything is fine, so maybe it's a bug of spice.
Comment 3 Uri Lublin 2015-05-13 07:52:14 UTC 
Moving to the X qxl driver.
This is probably a duplicate of bug 1192154 which has a fix
Comment 4 Pavel Grunt 2015-05-19 08:29:05 UTC 
It is happening with xorg-x11-drv-qxl-0.1.1-17.el6.x86_64
Comment 5 Christophe Fergeau 2015-05-20 13:20:08 UTC 
Does not happen with spice+cirrus but happens with vnc+qxl.
Comment 6 Frediano Ziglio 2015-10-14 12:57:32 UTC 
As it happened with xorg-x11-drv-qxl-0.1.1-17.el6.x86_64 (as Pavel reported on 2015-05-19) looks like bug 1192154 fix did not solve the issue.

Why this memory leak (wrong image caching) has not been fixed in RHEL7 as well (as of RHEL7.3) ?
Comment 16 Christophe Fergeau 2016-11-24 12:10:08 UTC 
Ah looks like this was missed, created https://bugzilla.redhat.com/show_bug.cgi?id=1398296
