10g instance crashing

Question

Our 10g instance continues to crash at intermittent times. There are no errors or shutdown procedures in the alert.log, just the restart process. There are no hardware issues either. Any ideas?

Answer 1

This server is dedicated to Oracle and we only have 1 instance running. Nothing else happens on this server.
Here is a portion of the listener.log at the last time it crashed.
