Bug Description

Binary package hint: software-center

On a lot of occasions, Software Centre pulls 100% processor load, for example:

Open Gkrellm or another tool for watching processor activity.
Open Ubuntu Software Centre.
In the pane to the right, single-click on 'System'.

The processor load reaches 100% in several minutes. It happens on two different computers.

Just noticed this today on my lucid -32bit machine.

Open software center, maximize the window, choose a package and click more info. Cpu usage jumps really high until you restore the window size or get out of the info page.

I guess my issue requires a separate bug report.
The issue I have only occurs when you view details of a package when the package doesn't have a screenshot and the window is maximized.

Strike my last comment, it does it with packages that do have a screenshot. Openoffice.org Word Processor is one.

I can confirm this bug.

In my case is only a few seconds (10 to 15), but I think that this is because of my processor (AMD X2 4400+). I'm using Lucid 64 Beta1 with all the updates applied.

The problem occurs when you select a large section, like "System", or "Provided by Ubuntu", the application turns unresponsive (the window turns grey) and one of the cores have a 100% utilization.

Now in version 1.1.23, it takes 30 seconds on my old machine. An improvement, but still annoying. Just opening Software Centre from the menu takes another 30 seconds with full load.

I wonder: Do the developers ever test their work on a machine as in the official minimal requirements?

Not running anything other than a browser and noticed the laptop became extremely hot to the touch. I checked the System Monitor and found everything under processes as "sleeping" with the exception of the System Monitor. The CPU was maxed at 100% and all other readings appeared normal. No hard drive activity during this event. The only way to I found to remedy the problem was to cold boot. Now it's back to normal range between 0 and 25%.

Well, it is going somewhat faster now, but I will still stick to Synaptic, in which I have never found a single bug.

Besides that: I think that original poster should be the one to close a bug report.
