Hi, this is a previously reported issue but we are tracking progress in a
private bug. I think we have a working patch though, so I'll keep you informed.

Comment 2 Binbin Wang 2008-08-04 08:59:21 UTC
One of customer in China also have the same problem!

The output of ps command.

any patch or workaround method?

Comment 3 Jonathan Kamens 2008-08-07 02:07:32 UTC
Is the the bug which causes me to see ridiculous %CPU values from procps with fedora rawhide (procps-3.2.7-20.fc9.i386), or is that a different bug?

For example:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
 3168 root      20   0 96852  20m 7748 S 424.4  1.1 363:21.90 Xorg

Comment 4 Jonathan Kamens 2008-08-07 02:07:58 UTC
Oh, Damn, never mind, I put that comment in the wrong ticket.

Comment 5 Daniel Senie 2008-09-02 13:48:08 UTC
We see this as well when we leave Virtual Machine Manager open on a machine for an extended time. The machine runs out of memory, and problems start cropping up. Interestingly, it's another virtualization item that then complains via email (due to a cron job failing). Only the subject line of the email and the contents are included here:

Subject: Cron <root@briar04> python /usr/share/rhn/virtualization/

Traceback (most recent call last):
  File "/usr/share/rhn/virtualization/", line 213, in ?
    debug = options and options.debug)
  File "/usr/share/rhn/virtualization/", line 50, in __init__
  File "/usr/share/rhn/virtualization/", line 123, in _load_state
    except PickleError, pe:
NameError: global name 'PickleError' is not defined

I've had to reboot servers that have gotten into this state. Haven't figured out what services to kick to avoid reboot.

Created attachment 315545 [details]
Add support for bonding and vlan devices (also plugs memory leak)

The attached patch fixes the memory leak. It is being tracked by a private bug to add support for bonding and vlan devices for bridges, and also happens to fix the leak :)

This will be in 5.3, but here is the patch in the interim.

Comment 7 Cole Robinson 2008-09-16 23:51:33 UTC
FYI, this fix has been committed and built. I'm just going to move this bug to ASSIGNED and leave it open until 5.3 is out, at which point I'll close it. For anyone with the proper access, the private bug we are using to track this is 443604.

Comment 8 Cole Robinson 2008-09-16 23:52:18 UTC
Ah sorry, the actual bug is 443680.

Comment 9 Cole Robinson 2009-01-16 14:41:20 UTC
Okay, fix is built and pending release for 5.3, so I am closing this bug.

Comment 10 Dave Oksner 2009-07-30 23:58:20 UTC
So, am I missing something, or was this left out of RH EL 5.3?  I have rhn-virtualization-host-1.0.1-55 installed.  It appears that this is the latest version and that it is from January 2008, before this bug was opened.

And, we're seeing the exact same messages as Daniel Senie reported in comment #5, or I wouldn't have come looking for an answer. :-)

Comment 11 Chris Lalancette 2009-07-31 12:32:52 UTC
So, the patch in the private BZ was committed to RHEL-5.3, so this issue should be fixed.  What version of virt-manager do you have installed, exactly?

Cole, do you have anything else to add here?

Chris Lalancette

Comment 12 Cole Robinson 2009-07-31 13:46:00 UTC
The traceback in comment #5 looks like an RHN bug, so Dave (Comment #10) should file a bug with them. I can pretty much guarantee that the original bug (memory leak) was fixed in RHEL5.3.

Comment 13 Dave Oksner 2009-08-04 16:22:08 UTC
Okay, thanks.  I'll try to track down what went wrong and where.
