GC overhead limit exceeded

[Nick Payne]

I'm running Eclipse 4.2.0 and Elysium 0.3.1.201208261140 on Linux Mint
13 amd64. Java version is Oracle Java 1.7.0_07-b10.

I just created a new LilyPond project in an existing folder containing
four ly files totalling about eight or ten pages of music. No subfolders
under this folder. After I clicked "Finish" in the new project dialog, I
could get no response from Eclipse. I started system monitor to see what
was going on and found that Java was using all four CPUs at over 90%.
After about a minute of this, Eclipse puts up an error dialog saying:
"An internal error occurred during: Building workspace. GC overhead
limit exceeded". After I ok that dialog, I get another saying that an
out of memory error has occurred and do I want to exit the workbench.

I already have -Xmx1g in eclipse.ini. Should I increase this - the
machine has 12Gb of physical RAM, and I notice that after starting
Eclipse without any project open, java is already using almost 0.5Gb of RAM.

See http://docs.oseems.com/general/application/eclipse/fix-gc-overhead-limit-exceeded
In short, change the -Xms setting to about -Xms512m.
I'm going to update the FAQ on this.
