Thanks IanW for the questions. Would it be possible to put in place a procedure for admins to ask questions to help diagnosis, when a bug is marked incomplete - These kind of questions are very helpful to have early?
It's a few days since the last similar event, but it will probably happen within the next week - I will try to drive to fail this way again. 1) I don't recall many situations recently when the computer has become totally hung, without there being an update icon present on reboot. Firefox usually has a number of windows open, with a number of tabs in each window. So I am not "absolutely certain" that it is totally due to the updater, but there is not much chance that the problem is "unrelated" to the updater. Q1) What should I be looking for in Syslog? re "Does this ONLY happen when update-notifier is downloading?" Firefox can slow the system down when lots of windows and tabs are open, and speed can be restored by closing a few tabs. But the system doesn't hang with firefox to the extent that there is "no control" - it just might be that the mouse response become intermittent. The system hang becomes unresponsive when there is no update icon showing - but the icon show on reboot. This suggests that the updater did not get as far as showing the icon before it hung the system. So the issue is not just "ONLY happen when update-notifier is downloading" but also if it has actually begun "Downloading", or was just about to beging downloading, having been notified that downloads were available. re "can it be reproduced by running Synaptic or 'sudo apt-get -d upgrade'?" it's a while since I did some synaptic "add programs" with many firefox windows open, but I do recall there being some crashes if there were lots of firefox windows open. I could check if the crash could be avoided by disabling the update- notifier, but I think I'll do that after the next (forced) crash, so I can collect syslog data after the crash. 2) The system become totally unresponsive - mouse cursor does not move at all. Keyboard does nothing. Q2) How do I restart X without mouse or keyboard control? 3) I will track memory usage. Is there a recommended program - I'd like to keep a log of the last 7 days on memory usage at 30 minute intervals, and the last 5 hours at 5 minute intervals? Thanks for your help. I hope these answers are helpful. And soon hope to be able to provide syslog info, top, and memory usage info. -- System goes slow when updates are available https://bugs.launchpad.net/bugs/241873 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
