Oracle 10.2.0.1.0 listener process stopped
There is probably not enough logged at the default level to give you any real insight to root cause, so the best thing to do is restart the listener at a higher logging level. Enter 

LSNRCTL&gt; trace admin
LSNRCTL&gt; save_config
LSNRCTL&gt; start


Then if it crashes again, you'll know why. You can also set the variables trc_directory, trc_file and trc_level to customize this behavior. 

Also your HOST=0.0.0.0 looks odd to me... Shouldn't that be the IP address of your host? What do you have in LISTENER.ORA?
