Initially I was using a ldappcng built from source, but I can
reproduce the behavior using this binary version:

http://www.internet2.edu/grouper/release/1.6.1/grouper.ldappcng-1.6.1.tar.gz

The details are:

skoranda@garlic:~$
uname -a
Linux garlic 2.6.32-5-amd64 #1 SMP Fri Sep 17 21:50:19 UTC 2010 x86_64
GNU/Linux
skoranda@garlic:~$
cat /etc/issue
Debian GNU/Linux squeeze/sid \n \l

skoranda@garlic:~$
java -version
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)

I will look into jstack as Chris suggests and get back to you.

Thanks,

Scott
