Update:
I tried this on a different machice, still connecting remotely to the DB2 server, and it worked ok. So it must be some sort of configuration issue :(

End update

I am working on a program that is querying a remote DB2 server for some data. In a test run, i am getting an error preparing a query. The query is nothing complicated, its like:

SELECT LIST_NBR, PARCEL_NBR FROM list WHERE PARCEL_NBR = '0540040'

I'm running basically the same query over and over, with a different value for PARCEL_NBR. (yes i'll add bind_params when things begin working). Anyway, regardless of where i start in my list, i get an error on the 1327th iteration. Even if i keep asking for the same values, it dies on the 1327 iteration.

Here is a VERY stripped down version of what im doing, which still gives the error:

use strict;
use warnings;
use DBI;
use DBD::DB2;
$ENV{'DB2INSTANCE'} = [...];
{

    my $db_handle = DBI->connect('DBI:DB2:FLEX', [user], [pass],
                                {   'RaiseError'    =>  1,
                                    'PrintError'    =>  1,
                                },
    )
        or die "couldnt connect to FLEX db $?\n";

    my $taxkey = '0540040';
    for my $i (0 .. 1400) {
        print "COUNT: $i\n";
        find_listings_for_parcel($db_handle, $taxkey);
    }

    $db_handle->disconnect();
}


sub find_listings_for_parcel {
    my ($db_handle, $taxkey) = @_;

    my $query = "SELECT LIST_NBR, PARCEL_NBR FROM list "
        . " WHERE PARCEL_NBR = "
        . $db_handle->quote($taxkey);

    my $query_handle;
    eval {
        $query_handle = $db_handle->prepare($query);
    };
    if ( $@ ) {
        print "QUERY: $query\n";
        exit;
    }

    eval {
        $query_handle->execute();
    };
    if ( $@ ) {
        print "QUERY: $query\n";
        exit;
    }

    $query_handle->finish();
}

The error I'm getting is:

...
COUNT: 1326
DBD::DB2::db prepare failed: [IBM][CLI Driver][DB2/SUN64] SQL0805N  Pa
+ckage "NULLID.SYSLH203 0X5359534C564C3031" was not found.  SQLSTATE=5
+1002

QUERY: SELECT LIST_NBR, PARCEL_NBR FROM list  WHERE PARCEL_NBR = '0540
+040'

This must be some sort of memory leak or resource clash, because it is doing the same thing over and over, and eventually dies after many iterations. I have tried with other PARCEL_NBR values, with the same result.

Oh, LIST_NBR is 'integer not null'
and PARCEL_NBR is 'varchar(50)'
Any ideas?
Thanks
