When you say the system froze again, is it a kernel panic? When you reboot does the system ask you if you want to save a dump file? Or, is the system non responsive and the only way to get it to respond again is a hard reboot?

SAVECORE(8) System Manager's Manual SAVECORE(8)
NAME
savecore - save a core dump of the operating system
SYNOPSIS
savecore dirname [ system ]
DESCRIPTION
Savecore is meant to be called at the end of the /etc/rc file. Its function is to save the core dump of the system (if one was made) and
to write a reboot message in the shutdown log.
It saves the core image in the file dirname/core.n and its corresponding namelist in dirname/unix.n. The second argument is the namelist
for the system which made the core image; the current system is always assumed to be /unix. The trailing ".n" in the pathnames is replaced
by a number which grows every time savecore is run in that directory.
Before savecore writes out a core image, it reads a number from the file dirname/minfree. If there are fewer free blocks on the file sys-
tem which contains dirname than the number obtained from the minfree file, the core dump is not done. If the minfree file does not exist,
savecore always writes out the core file (assuming that a core dump was taken).
Savecore also writes a reboot message in the shut down log. If the system crashed as a result of a panic, savecore records the panic
string in the shut down log too.
If savecore detects that the system time is wrong because of a crash (the time in the core image is after the current time), it will reset
the system time to its best estimate of the time, which is the time in the core image plus the elapsed time since the reboot. It announces
the time that it set when this occurs.
FILES
/usr/adm/shutdownlogshutdown log
/unix current UNIX
BUGS
The method used to determine whether a dump is present, and to prevent the same core image from being saved multiple times, is not elegant.
This information should be passed to init by the system; however, this is difficult because the system may have to be rebooted a second
time if the root filesystem is patched.
