spicec thread backtraces during hang

Description of problem:
I have single guest using spice on my F14 host. The guest is also running F14. Both guest and host are x86_64. The guest is using qxl drivers. I have the following on the qemu command line:

-vga qxl -spice port=8137,disable-ticketing

I am connecting with:

spicec -h localhost -p 8137

spicec frequently hangs in normal usage. Specifically, it becomes unresponsive to the mouse and keyboard. A regular 'kill' will not kill it. I have been killing it with -9, although I have not tested if any other signal will do it. I have not yet noticed a pattern in the hangs. They happen many times a day, making using spicec a painful experience. I have not noticed any issues in the guest, and I can reconnect immediately after killing spicec.

I have attached a file containing backtraces of all spicec's threads during a hang. I will also attach qemu output for my current session. spicec has hung once during this session, and I have reconnected. I have also resized the guest's display. Unfortunately I didn't make a note of which point in the log the hang occurred.

Thanks for using spice, and thanks for the bug report. The bt of the spice client while it hangs is exactly what I needed.

I've done a scratch build with a patch hopefully fixing this, please test it:


Comment 3 Hans de Goede 2010-11-17 06:40:17 EST

Note if you see another hang with the scratch build, please do a bt of all threads of the client again.
Comment 4 Matthew Booth 2010-11-17 08:11:30 EST
Thanks for the fast response. I've installed the scratch build and will report on how the testing goes.
Comment 5 Hans de Goede 2010-11-18 09:23:41 EST
Matthew, thanks for testing. Any feedback on this ? (such as did not hang for an entire day, looks fixed :)
Comment 6 Matthew Booth 2010-11-18 10:18:26 EST
This hasn't hung now for 2 days. Certainly looks fixed.
Comment 7 Hans de Goede 2010-11-25 05:58:24 EST
