I rebuilt nagios and did not strip the installed binaries to get that
backtrace.  What else would I need to do?  Rebuild the OS with a knob in
/etc/src.conf?  I suppose I would also need to rebuild and reinstall any
ports on which nagios depends.

I have theorized that to be the case.  I really don't know how to find
out what the other thread is doing.

With my backlog of work at the moment, I'm probably just going to be
happy with the workaround/bandaid of disabling "J" in malloc options.
Maybe I will be able to get back to it in a month or three.

I really do appreciate the replies I have gotten.
