vino-server takes up 100% CPU load when option "configure UPnP routers" is set

[Rüdiger Kupper]

After upgrade to vivid, vino-server takes up 100% CPU load.
(There is an older bug report that sounds similar, but has been fixed in the past: bug #31037 I do not know if it is related.)

Update: The bug is reproducibly related to open "Automatically configure UPnP routers". Only if this option is set in vino-preferences, the high CPU load occurs. Unchecking the option makes vino-server run normally.

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem here on 15.04. I removed the UPNP and vino stopped taking up 100% of the cpu

Please:

1. Report to <https://bugzilla.gnome.org/>.
2. Paste the new report link here.
3. Set this bug status back to "confirmed".

Thank you.

Can confirm, this bug is still in Ubuntu 15.10 (Wiley) and occurs only when UPnP is enabled.

[Rüdiger Kupper (ruediger.kupper)]

Thank you, Logicwax. I have now filed a bug report at the GNOME bug tracker:

Running Ubuntu 15.10 and im getting this behavior even when that option is unchecked... i'm going to try cycling the configuration to see if that fixes it. It seems to only occur after 48-72 hours of uptime.

[Rüdiger Kupper (ruediger.kupper)]

William, thank you. I cannot confirm your findings. With me, the effect is directly coupled to the uPnP-option setor unset. I run a server with uptimes well over four months, and the problem never appears while the option is unset. However, it appears reproducibly when the option is set.

[Rüdiger Kupper (ruediger.kupper)]

Oops, that was meant to read: Well over four weeks. But I guess it makes nothing of a difference regarding this bug.

I think I should have put my comments here... instead of https://bugs.launchpad.net/ubuntu/+source/vino/+bug/31037/comments/102

[GingwinJoe (atlantide)]

Moreover, since I cannot set the UPnP option on and I cannot manage the WiFi APs and routers around here, I am not able to use the VNC server (Remote Access) at all.
So this bug is very high - top priority - a show stopper in my book.
My only solution for now is to install a different server all toghether.

[w-sky (w-sky)]

Same with me here, except that I have to log out and log in (or restart) after I have changed the UPnP setting to "off". Until doing so vino is running wild.

Nevertheless, when the machine is running fine and I switch UPnP at Desktop Sharing "on", vino immediately is again at 100% load on one core.

Problem appeared after upgrade from 14.04 LTS to 16.04 LTS, 32 bit Atom system, no GPU.
