Hello, I have an IBM xSeries x335 Dual Xeon processors and 4GB memory which have a system crash. The system locked up hard and only a hard reboot would recover the system. I could only get the kernel panic dump. There was no core dump.

This particular system is running LDAP, NFS, Samba, CUPS, and DNS. The other systems are LTSP servers which running far more applications and services than this system and the question is why did this system crashed so hard with absolutely no warning? I don't believe it is hardware or the kernel since other systems would exhibit this problem as well. ------------------------------------------------------------------ Fanying Jen Email: fanying@xxxxxxxxx Pgp Key: http://fanying.fynet.com:11371/pks/lookup?op=get&search=0x6B92EAC5 The Fanying Jen Network http://www.fy-net.com/ http://www.fynet.com/ ------------------------------------------------------------------ - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
