the default settings for the concurrent garbage collector seem to size the young generation
way too small (At least for heap sizes of 1GB or larger.)   Can you also let us know what
version of the JVM you are using?

Sure.  This is running under CentOS 5.6, with epel, rpmforge, and 
jpackage repositories added.

[root@idxst0-b ~]# java -version
java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.0-b11, mixed mode)

I used to make the java RPMs, 
as explained here.  Looks like I can go to now:*

P.S. Tom, thanks for all the good info on the Hathi Trust blog.
