Attached is a set of full gstack dumps taken at 1 second intervals.  The 
majority of it consists of select/poll/etc... calls that I filtered out 
last time, but left in this time for context.

One of my coworkers wanted me to mention that we use long running ldap 
connections (bound to a user's session for the duration of that session 
unless the session is replicated to another jvm instance).  I know that 
isn't really standard, but I don't think that should cause these problems.

Tomorrow I'm planning on writing a forking bash process to push the 
exact same requests under the exact same load at 389 to determine if it 
is a problem caused by the java code or container itself (by eliminating 
them completely).  I'll keep you posted on the result of this.

Thanks,
Justin
