Any help would be appreciated.
Oracle 8.1.7 on Windows 2000 Server.

We have a complex process here, written in VB. It takes about 4 hours to run. Last week it crashed with ORA-03113 showing on the user's screen, but no trace or log files. It's crashed twice today, again with no files generated. This is a major process and I'm under pressure to come up with a solution. I've googled, and checked Metalink, but the error is so general that without an error file I don't know where to start, other than blindly applying "solutions" and hoping one works. I tried tracing the session, but I ended up with 5Mb of FETCH/EXEC in a cursor loop within seconds. There is a lot of VB code, cursors and temporary tables used, and it's politically difficult to re-write. Anyone have any idea where I can start looking for the problem?
