Bug Description

Binary package hint: update-notifier-common

Since yesterday I'm experimenting big system slowdowns. I did my research and found out that the programs that were causing it were update-apt-xapi and apt-check. I see there is a bug report filed against the first one (https://bugs.launchpad.net/ubuntu/+source/apt-xapian-index/+bug/363695), but not for the second one. See this screenshot: http://launchpadlibrarian.net/28844564/memoryleak.png . Both processes eat up almost all the computer memory.

Package: update-notifier-common, v. 0.76.7
Ubuntu release: 9.04
Computer: HP Pavilion, 1.8 GHz Core 2 Duo, 3 GB RAM.

What to do to reproduce the bug:

1. Open Synaptic/Update Manager
2. Check for updates/install new software
3. When the check/install is finished, update-apt-xapi and apt-check show up and cause extreme slowdown. (It even caused a total hang to my computer and I had to use the Alt-SysReq-REISUB trick to get it working again). Nothing like that used to happen before. I don't remember if those packages were updated recently.

I have already removed the apt-xapian-index package, but apt-check is still causing trouble (I can't remove it because network-manager and network-manager-gnome will be removed too if I do so). If any other information is needed, please tell me.

I forgot, just before the total hang happened, update-manager reported with an error message that there wasn't enough memory to allocate.

I'm having the same problem on my Jaunty, after updating software through Synaptic, "total hang" it is. Only the hard disk grind makes me realise the machine is still running, I believe the process uses up all my memory as well as swap space. So is there a way to disable apt-check?

@benjaminzsj I forgot to say this before, i moved the apt-check executable to another folder and that ended the hangs. I haven't noticed any adverse effects, which, must exist for sure. Any ideas, anyone?
