full pstack of the (running)hung process is at
/net/cores/cores/64439244/0211/pstack.20040210

SA is not showing thread 16 when I try to examine with it.

Core file is at
/net/cores/cores/64439244/0211

all libs are in /net/cores/cores/64439244/0211/app with the exception of the customers /usr/lib/lwp libthread libraries with are in the base dir /net/cores/cores/64439244/0211

should be able to simply run opencore to launch into it.
