DBI / DBD-Oracle problem, database disconnected

 DBI / DBD-Oracle problem, database disconnected

I am having an intermitten problem.  I have a perl script that generates
web pages pulling data from an Oracle database.  I am using:
 Perl: 5.00503
 DBI: 1.13
 DBD-Oracle: 1.03

 I get this entry in the error_log:
 DBD::Oracle::db prepare failed: ERROR Database disconnected at
/path/to/file/openwork.pl line 313.
 [Tue Aug 15 0:57:49 2000] [error] Can't prepare SQL statement: ERROR
Database disconnected

 Now if I reload the web page, _Most_ of the time, it will then run.  On
the occasions that it does not reload properly, if I give Apache a -HUP,
it always works.

 At the beginning of the script I have:
   || die "Connect Failed: $DBI::errstr";

 I then call subroutines, and included in them are:
 $sql = "SELECT stuff FROM table WHERE condition";
 $cur = $db->prepare("$sql")
   || die "Can't prepare SQL statement: ", $db->errstr(), "\n";
   || die "Can't execute SQL statement: ", $cur->errstr(), "\n";
 while (($stuff) = $cur->fetchrow_array) {
   do some things here...
 warn "Problem in fetchrow_array(): ", $cur->errstr(), "\n"   if

 I often call multiple subroutines, some with database connections. At
the end of the script I have:
   || warn "Failed to disconnect: ", $db->errstr(), "\n";

 Looking through this, I notice I don't have any finish().  Could that
be part of it?  Anyhow.  Is there a way to capture the disconnection and
force a reconnect?  Any ideas are welcome.
