Description Dick Porter 2009-08-20 11:44:18 UTC

Description of problem:

I noticed the 'YumBackend.py get-updates' process had wedged when a yum install told me it was blocking on a 38 day old process.  I killed the YumBackend process, and a new one was respawned that noticed there is a distribution upgrade available.

This then proceeded to notify me (54 times at once so far, and no end in sight), causing the Xorg process to consume close to 100% CPU and the system therefore unresponsive.

I'd rather not reboot to clear this notification backlog as I have a large amount of work state that would need to be recreated if I did.



Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Not update to Fedora 11
2. Wedge the yumBackend.py process that checks for updates
3. Wait 5 or 6 weeks
4. Kill the yumBackend.py process
5. Spend several hours clicking on dozens of simultaneous notifications while trying to preserve work
  
Actual results:

Dozens of simultaneous notifications


Expected results:

One notification

Difficult to reproduce, but I think I can fudge something.

Comment 2 Richard Hughes 2009-08-21 13:01:17 UTC

Hmm, I've been trying for a little while, but I can't reproduce this on F11 or rawhide. Does this still happen in F11?

Comment 3 Dick Porter 2009-08-21 13:05:17 UTC

No idea, I'm not running F11 yet - and even if I were it's a bit difficult to trigger in normal use :)

Comment 4 Richard Hughes 2009-08-21 13:35:36 UTC

Right, I've reviewed the codebase we use in F11 and rawhide, and there's no way we can send multiple requests in a short amount of time. I'll close this one for now, but if you can reproduce with F11, I would be interested. Note., F11 seems to get itself wedged a lot less than F10!
