** Description changed:
libvirtd fills the memory, until the libvirtd process gets killed. This
happens over a long time.
- This server (info by ubuntu-bug) has 4GB of memory and an uptime of 27
days. Some KVM machines have been active during that period. The last 4 days
before the crash, no virtual machine was running on the server, but libvirtd
slowly filled memory.
- Another server has 32 GB of memory and active virtual machines. It took a
few weeks more until memory was completely filled.
Steps to reproduce:
- Start libvirtd
- Wait a long time

+ ======
+ SRU:
+ * IMPACT: If affected, libvirtd will eventually leak all memory, and OOM the
system.
+ * ADDRESSED: Applied patch solves two memory leaks by freeing memory on
function exit conditions.
+ * PATCH: As attached from Nigel Jones below. He has also submitted this
upstream as well.
+ * TEST CASE: In some cases, you can reproduce this issue by running "top -p
$(pidof libvirtd)" in one window, watching RES memory usage increase, while
running "while true; do sudo multipath -F; sudo multipath -v4; done" in another
window. Due to a race condition (see Bug: #585027), this will sometimes not
reproduce the issue by itself. In these cases, you can "simulate" the race
condition by "sudo dmsetup remove <string>", and then running the commands
above.
+ * REGRESSION POTENTIAL: Patch is pretty simple, clean. Regression potential
should be minimal.
