Bug Description

On an Edgy AMD64 box installed with Beta CD, I checked for updates today (all the stuff uploaded after the beta freeze), then told update-manager to update all selected processes.

Right now, it's in the middle of downloading, and update-manager's Resident Memory is being reported at 120MB (its child synaptic is "only" using about 40MB). Killing update-manager indeed frees up around 120MB of RAM.

This seems like an unusually high amount of memory for an update applet to be using... Is there something that can be done to reduce memory requirements? Even on a system with 512MB of RAM, 120MB is a pretty big chunk... heck that's as much as Azureus with 2 active torrents or Openoffice.

Ok, maybe it is.... let's call it a dupe unless we figure otherwise.

A lot of this RAM usage is due to maped libraries and the mmaping of the apt cache (use pmap -x on the update-manager pid to see the details). This is not "real" ram.

But there is a memory leak that I haven't yet tracked down too :/
