Sounds like a network problem, beware of the network outages during off hours.  Re-write in perl and run on the db server :).  Change the times it runs and see if you can recreate the problem.

Dennis,

    I have been plagued by a similar problem and have a fix if it fits.  Check
the statements where the 3113 is coming from.  Are they going to a remote
database?  And if so, are the tables on the remote database analyzed while the
local tables are not?  Then the fix is to delete the statistics on the remote
database.  I believe it to be a bug in 8.1.6.

I have a developer that wrote a VB program using ADO, connecting to Oracle
8.1.6 on a Compaq Tru64 server. One program of his runs for hours each
night, and sometimes receives an ORA-03113 end-of-file on communication
channel. Not consistently, just sporadically, and at varying amounts of
time. I have been unable to find anything in the server logs. We have traced
the program and the error occurs during different SQL statements. Followed
most of the tips I've located on solving ORA-03113 errors. I am coming to
the conclusion that maybe the only solution will be to upgrade Oracle and
hope that solves the problem. Unfortunately we can only upgrade to Oracle
8.1.7.4. Does anyone have any other ideas? Thanks.
