Exception when insert into DB (GPF file created)

[mrkitos67]

I'm using Mercator 6.7 to transform EDI file and put data in a Oracle 10G database.
I've got a map, it has two output cards to insert header and detail data, in DB tables HEAD and LINES. Map is working correctly. Now, I've added sevaral fields to LINES table, and without any modification on typetree map works on test environment, but when I deploy map into production environment, sometimes (not always) I get this error:

<TargetReport card="2" adapter="DB" bytes="151" adapterreturn="-2">
<Message>Exception occurred</Message>
</TargetReport>

When it occurs, a GPF is created with this content:
----------------------------------------------------
-- GPF report - Thu Jan 24 09:02:20 2013

Exception code: 0xc0000005
Exception address: 0x77e5bb3c
Number parameters: 2

Connection: 0001e4f2
Type: DB
Operation: Put
Command:
---------------------------------------------------

I've DB trace files enabled, but error doesn't write anythig in these files.


Can anybody help me? How can I know what's happening?

Thanks

you need to look at the DB trace file. It will give you a better, more relevant, return code.
