red hat 4 crash

Hi All,

If red hat 4 crash. How do I find out the error info or the last log info? I tried dmesg and /var/log/messages, it's not there.

Thanks in advance.

Look at the logs for the services you have running. If it is not in logs then you don't have too many options. Look for core dumps as well. Were any changes made recently? Start there. If not then look for power issues, make sure memory is not the problem as well by doing a full memtest (NOT JUST THE BIOS MEMORY TEST!). Usually if no logs indicate problens you can trace a hard crash back to hardware, heat issues, or power.

Under Linux core dump doesn't get generated by default when a system crashes, unlike solaris. You have to configure either of netdump, diskdump or kdump in order to get the core or vmcore. Look at redhat.com | Red Hat Support for details on configuring netdump.

Regards,
A.
