Solaris

I am supporting a server running Solaris 4.3.The server is not having ddicated system administrator and i am requred to do minor maintenance tasks.l From few days, The server is automatically crashing and i just reboot the server. I also do not see anything in /var/adm/messages that can give an idea as to actually why the server is crashing. There may be some serious problem going on with the server that needs to be taken care of as soon as possible.I have read that a crash dump file is generated when the server crashes.

i did a

Code:

find . -name '*crash*' -print

and received the following output

Code:

./usr/etc/crash
./usr/share/man/man8/crash.8
./usr/share/man/man8/crash.8s
./usr/kvm/sys/sun4m/OBJ/subr_crash.o
./usr/kvm/crash
./export/exec/proto.root.sunos.4.1.3_U1/etc/crash
./export/exec/proto.root.sunos.4.1.3_U1/var/crash
./etc/crash
./var/crash

but all of the crash files are 0 bytes. Can any one suggest the correct location of the crash file and as to where i should look for this file.
Please let me know if am to post some other detailed information


Thanks in advance

cd /var/crash/`hostname`
any files in there?
once the system is up, what do you see in the messages file, prior to the system going down?

what h/w model are you using? Is the firmware upgraded to the recommended or whichever latest?

Does the system run on only one power supply?

How often that the system goes down?

What do you mean by crash? you saw the panic string when the system come down or it just powered off or just dropped to ok> prompt?

Are the boot disks mirrored? Any errors that you find on the OS? Be it HDD problem or whatever..
