HELP Ada on the HP TAC-3

[Casey259]

I need all the help that I can get.  We are running a custom application
on an HP TAC-3 under HP-UX verstion 9.01 (I think).  The application
spawns off 12 other processes that service several interfaces (rs232,
ntds-e interface {GET card}, ...)
The problem is that the application will run for several hours and then
for no reason (or at least on that I can think of or I would fix it) the
system re-boots.  Question one is: is there a program out there that can
decipher a core file to
determine why the system re-boots.  Question two is: is there a way to
prevent the re-boot to determine what the problem is.

The applications are written in Ada (VERDIX that is).  

Thanks in advance
