Eclipse will throw
GC overhead limit exceeded error when it runs out of memory, normally while performing memory-consuming operations such as building workspace on big projects.
Here's how the error looks like;
An internal error occurred during: "Building workspace". GC overhead limit exceeded
To fix this problem, you'll need to allocate more memory to your Eclipse instance. To do this, go to the Eclipse installation directory, and locate the
eclipse.ini file. The file might look like the following;
-startup plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar --launcher.library plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.2.R36x_v20101019_1345 -product org.eclipse.epp.package.php.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -XX:MaxPermSize=256m -Xms40m -Xmx384m
To increase the memory allocation for your Eclipse instance, edit the number in the following lines accordingly.
The number is the amount of memory, in Megabytes.
You can also increase the value of
MaxPermSize, as the following;
Restart Eclipse for the changes to take effect.
