1) What are the servers that don't have a problem?

One is a single AMD Athlon 64 2800+, running the 64-bit Sun JDK (same version).

The other is a dual AMD Athlon MP 2000+, running the 32-bit Sun JDK (same 
version).

And the "bad" server has "8" Intel Xeon E5310 CPUs running the 32-bit Sun JDK (it is indeed a dual quad-core, not a quad dual-core, as I incorrectly typed in my original post).

2) How much RAM is on each server?

The Athlon 64 has 1.5 GB RAM (2 GB swap).
The dual 32-bit Athlon has 1 GB RAM (2 GB swap).
The "bad" server has 2 GB RAM (2 GB swap).

3) Is the JDK 32- or 64-bit on each server?

32-bit on the two 32-bit machines, 64-bit on the 64-bit machine.

4) What's the Java heap size for Tomcat on each server?

I've played with heap size quite a bit to no avail.   Currently, all are 
running 768 MB with the following JDK options:

JAVA_OPTS="-Xms768m -Xmx768m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=128m 
-XX:MaxPermSize=128m"

5) Are you using the same file system on all three servers?  What is it (ext3, 
reiser, ???)?

Yes. ext3 on all three machines, all are running current Fedora Core 9 distros (well, except for the new kernel which came out yesterday).
