Hi,
We have already tried using ora_maxarray_numentries and other similar
attributes unsuccessfully.
Martin found that immediately before the error the following message is written:
{{ execute callback CODE(0xb832be8) being invoked
However we have done a dbi_trace with 1000 elements in the arrays (which
works!) to see whether a similar message is logged and it is, so I would not go
into that direction though. Will setup a test environment using the latest DBD
and DBI versions to see whether the leaks in DBD are causing this behavior.
Thanks.
Best Regards,

The reason I pointed out the execute callback is that it is only called just
before the failure and we cannot see from the trace what code is in it. If we
cannot see the code who knows what it is doing?
1 -> FETCH for DBD::Oracle::st (DBI::st=HASH(0xd077218)~INNER 'ParamValues')
thr#8916008
1 <- FETCH= ( HASH(0xd0758e8)7keys ) [1 items] at /home/
Might have been interesting if we knew what was in it.
Perhaps you could get ParamValues just before execute and if execute fails
catch it and Dumper them.
use Data::Dumper;
.
.
my $pv = $sth->{ParamValues};
eval {
$sth->execute;
};
if (my $ev = $@) {
print Dumper($pv);
die $ev;
}
However, I still think testing the latest DBI/DBD::Oracle is the best thing to
do first.

As Martin said that is rather old version of DBD only 3 since native
exe_array was introduced 1.18, and I rember there being some leaks in early
version of the native exe_array.
If you can upgrade you DBD.
Yyou might try to set the 'ora_maxarray_numentries' on you binds as well
as that works on the Oracle side of things to limit memory.
As it runs stands alone as you say it might be that the things you are
binnding are not being released by perl as a referace to them may still exist.
Cheers

you can try the latest versions so we can at least see if the problem is already
fixed? You can do this without actually installing (overwriting) your existing
versions (ask if you are unsure how to do this).
