Bug Description

Binary package hint: unity

I have been testing Unity 2d under Maverick and I noticed that Unity Places leaks arround 260 mb of Ram of my 1gb whenever I perform a search on it's search box. It only happens if I keep the letters typed in the box (In current version the search box doesn't clear when Places launches the application) There is no problem whenever I clear the search box before Places exit out. Software Center says my current version is: 0.4-0ubuntu1~bzr405
Last time "Upgraded" was February 11.

Here's a screenshot attached from Unity Places leaking over 270 mb.

Hope this helps :)

Thanks for the bug report Mariano.

So, leaking memory is when the memory is never released during the lifetime of the process. I think what you are seeing here is rather a high usage of memory when search results are displayed.

Can you start a search and then execute the following in a terminal and capture the entire output?

ps aux

I don't think this issue should be dismissed anyway. Should I open another bug report and replace "Memory Leak" with "High usage of memory during"?

Don't worry the bug is not dismissed in any case.

Looking at the output of ps, unity-2d-places is using around 108MB of resident memory. That's a bit high and deserves further investigation.

summary:	- [dash] Memory leak when performing a search + [dash] High memory usage when performing a search
Changed in unity-2d:
status:	Incomplete → Confirmed
