Hi Bryan -
We're big fans of kdb around here, if you could compile with kdb, break
into it when you lock up, and do a backtrace on some (or all...)
of the processes, that would be a good start.
kdb> ps will give you a process list
kdb> btp <pid> will backtrace <pid>
kdb> bta will backtrace all pids
