[Bug 571093] Re: libvirtd eats away more memory over time

[Nick Brand]

I've got something similar happening on Lucid. I rebooted a new server
last night, and this morning libvirtd is using about 5GB of memory,
without any virtual machines running. Looking at my munin graphs, this
appears to have been happening on both of my new servers for the past
few days, with the most extreme case of libvirtd using all 48GB of
memory over the course of two days.

Setting the libvirtd log level to 2 displays a lot of:

23:07:15.340: info : udevGetDeviceProperty:111 : udev reports device 'sdc' does not have property 'DRIVER'
23:07:15.343: info : udevGetDeviceProperty:111 : udev reports device 'sdb' does not have property 'DRIVER'

Sometimes these appear multiple times a second, other times they only
appear every 20 seconds. Both devices (sdb and sdc) are being used by
multipath, and are mapped to /dev/mapper/mpath0, but I'm not sure why
libvirtd cares about them. Nothing else is showing up in the logs, and
loglevel 3 displays nothing.

The setup is two Dell R710 servers accessing a shared Dell MD3000 SAS
array. OS is 10.04 AMD64 server, with all patches applied as of the
morning of May 6th.
