Jalview uses too much memory

Jalview Discussion

Hi Lee.

I’m glad Geoff and Chris have helped you here. Regarding the openJDK issue, I believe there is a bug lodged with openjdk since many swing applications seem to exhibit this problem, which may be due to the java desktop implementation provided by the openJDK runtime.

If you know of any java apps that use a desktop window like jalview that don’t show this problem on openjdk then please let me know !

Jim.

Okay, I think I’ve tracked this down to a java bug. I can reproduce it
with either OpenJDK version, but scrolling is fine with Sun Java.

Thanks for all your help. Cheers,
Lee.

Ah. Ok. That was silly of me. Thanks for the answers.

There is also the issue of the visual garbage on scrolling? As I
mentioned, this seems much better in 2.8 (the “install anywhere”
version) as opposed to the 2.7 (Ubuntu repository version). I’m not sure
if this means the bug has been (somewhat) addressed? I’d prefer to use
repository versions generally, so they stay updated.

Cheers,
Lee.

Indeed. 99% free not 99% used!

I think you might be misreading the values.

The figures are telling you that 99% of the memory is available. Not 99%
in use. Try loading/creating some multiple sequence alignments, you should
see the percentage number go down indicating you’re using up some of your
free memory.

Hope this helps.

Hi Jim,

I’m not sure. I’m using the internal values from within Jalview, as per
the bottom left of the screenshot.

Cheers,
Lee.

Hello Lee.
Are you sure you aren’t looking at the virtual memory footprint ? Java
requests a large amount of cache for its runtime environment heap.

Hi,

I’m having a problem with jalview using up way too much memory. It seems
to have allocated about 3.5 GB, and uses 99% of it [1], even with no
windows open. I’ve tried installing 2.7 from the Ubuntu repositories,
the webstart version, and also the “install anywhere” version. In
addition, as per the linked screenshot, I have visual artifacts when
panning. This seems much worse in 2.7, as the “install anywhere” version
(2.8) appears to correct itself after a second or so. I guess this might
be related to the lack of memory available.

I’ve tried different java versions too (using the “install anywhere”
version of Jalview):

java version “1.7.0_25”
Java™ SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot™ 64-Bit Server VM (build 23.25-b01, mixed mode)

java version “1.6.0_27”
OpenJDK Runtime Environment (IcedTea6 1.12.6)
(6b27-1.12.6-1ubuntu0.13.04.2)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

java version “1.7.0_25”
OpenJDK Runtime Environment (IcedTea 2.3.10)
(7u25-2.3.10-1ubuntu0.13.04.2)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

All have the same problem. I’m using Kubuntu 13.04.

Cheers,
Lee.
