Eclipse Memory Leak

Biggles · Posted: Thu Feb 24, 2005 1:34 am Post subject: Eclipse Memory Leak

I'm having a problem with a massive random memory leak in Eclipse. It runs fine for up to an hour, then suddenly the memory usage of X skyrockets until it's using over 500MB (I have 512MB of RAM and 256MB of swap). If I close Eclipse at this point (which takes a lot of grinding), X's memory usage drops to around 200MB. I never had this problem before I started using Eclipse yesterday. I have version 3.0.1-r2 installed, and I'm using the CDT C/C++ thing installed from the eclipse website through Eclipse's internal upgrader thing.

Any ideas?

More info: I tried using the binary from the eclipse website, but it had the same problem. This makes me think it's a problem with the Java GTK stuff causing memory leaks in X.

I'm using the exact same version as you (CDT plugin version 2.0 also) and I'm running across issues when saving files. I managed to emerge after several issues but had to manually unzip the CDT plugin because Eclipse freaked when it tried. But I digress...

When I go to save something (anything, regardless of size) my CPU usage spikes to 99% for about five seconds, then recovers. I used to love Eclipse, but has it always had these kinds of issues?

By the way.... are you fairly new to New Zealand? I've known of someone who goes by Biggles that used to live in Melbourne.....

Nope, I've been here all my life.

I do notice occasional high spikes (up to 100%) in CPU usage, but only for a second or so. I had put these down to it being written in java. I had to run Eclipse as the root user to install the CDT plugin through its installer (just a permissions thing), but it worked fine there. What did it do when you tried?

I did, finally, track down the memory leak yesterday. If you use the gtk-qt theme engine for gtk apps, and you get huge memory leaks in eclipse, you probably need to change which theme engine you use for gtk. There's some kind of weird interaction between gtk, qt and java that produces a huge memory leak.

I wound up with the almighty "java.lang" error when I tried to install CDT neatly. It said nothing else. But it probably was a permissions issue as I wasn't root when I tried.

So... how exactly would I change the theme engine for gtk? If it matters, I'm in Fluxbox.

And I'm envious of you for living in New Zealand your whole life.

I've noticed the same problem with Azureus, and it really does seem to be the interaction between the gtk-qt theme and SWT/GTK somehow.

I've been having to restart Azureus 1-2 times daily due to excessive memory consumption (300MB and upwards, with 4 torrents running), and never thought of checking the theme. :-)

Anyway, I just passed a link to this post to the author of gtk-qt just to let him know, in case nobody else had done it yet.

Trejkaz:

Have you considered other bit-torrent clients? I tried Azureus and absolutely hated it. I just have BitTornado because it's really simple and easy to use and works well with partial downloads with ABC in Windoze.

Jengu:

Thanks. Emerging gtk-theme-switch now.
