First check your /etc/rc file to see if contains a command
'/etc/savecore directory_name'. This line causes a core image
to be saved in the named directory when rebooting after a system
crash. Also check to make sure that this directory is large
enough to handle the core image. You space requirements will be
(the size of /vmunix) + (the size of memory).
example:
if /vmunix is size 286720 on an 8Mbyte system,
the amount of space needed in the directory
would be (286720 + 8000000).
You may want to dedicate an entire filesystem for this purpose.
For futher info see savecore(8).
