Description Marc-André Laperle CLA 2014-05-14 15:09:08 EDT 
Eclipse Platform 4.4.0-I20140512-2000
Ubuntu 14.04
GTK 3.10.8-0ubuntu1
OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1)
SWT_GTK3=1
UBUNTU_MENUPROXY=0
LIBOVERLAY_SCROLLBAR=0
-Xmx1040m

After resizing my views for a few seconds (or even faster, resizing the whole window), Eclipse uses a lot of memory. The java process (Eclipse) is using 3GB and Xorg is up to 2.5GB. I don't see anything obvious using Sleak so the leak is probably at a different level than your typical missing dispose() call.

I tried to use Valgrind + Massif to look at memory allocation but my JVM crashes. Any tips on troubleshooting native memory issues in Eclipse?
Comment 2 Marc-André Laperle CLA 2014-05-21 20:11:09 EDT 
I can't reproduce this on Ubuntu 13.10 and Fedora 20 so it must be a regression in Ubuntu 14.04. I will close this as NOT_ECLIPSE for now since the cause of the bug is most likely in a package provided by Ubuntu and the fix will most likely happen there.

Might be due to new theming in Ubuntu 14.04

Matthew, when you have some time, can you test this on trusty (14.04) again? I can't reproduce it on 14.10. I'm using Eclipse 4.5-I20141125-0800.
Comment 5 Marc-André Laperle CLA 2015-01-12 23:51:40 EST 
I can't reproduce this on Ubuntu 14.04 anymore.
