Oracle is Spinning its Wheels

I'm running Oracle under RedHat 6.2, and it's been flawless, however just this week Oracle has started hanging up while using 100% of the CPU. The memory usage of that process gradually increases over time, but is still only using about 25MB after 8 hours of doing this.

It's Oracle 8.1.7.0.0 running on a Xeon/1Ghz machine with 1GB of RAM and about 200 GB of disk space. How do I diagnose the problem? I can still login to the server and execute simple queries, but if I do anything complicated (including a sort) then it'll sit there "forever" doing nothing at all. "dbshut" acts the same way, even if I tell it to perform an immediate shutdown, it'll sit there waiting for something. There is one error in the alert log:

Tue May 28 09:57:07 2002
Errors in file /u01/oracle/admin/dur/udump/ora_2410.trc: ORA-00600: internal error code, arguments: [723], [52680], [52680], [memory leak], [], [], [], []

Any advice?
