ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []

Hi,
After a long time I have an error of ora-00600.
One of my Database is Oracle Express10.2.0.1.0

Cause:
In log we were receiving these errors.
Oracle Server was not resolving HOSTNAME.

Mon Jan 7 14:58:48 2008Errors in file /usr/lib/oracle/xe/app/oracle/admin/XE/udump/xe_ora_2462.trc:ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []USER: terminating instance due to error 600

Solution:
added an entry for localhost in /etc/hosts.
open /etc/hosts file
vi /etc/hosts
:0:1 localhost.localdomain localhost
alter this to ....
127.0.0.1 localhost.localdomain localhost
or
ip_of_your_DBbox localhost.localdomain localhost


after that now check

-bash-3.1$ sqlplus
