Data Abort & Prefetch Abort

Hello.

In my PPC2003 application (CF2 Sp2 with SqlCE 3.1) when i try to insert or
update the database (my SDF is on Secure Digital) the Debugger sometimes
returns me messages like this:

If i detach the debugger from my app, sometimes my application crash
suddenly.

I always open/close connection (SqlCeConnection) when i talk to DataBase to
prevent Opened Connections when the PPC go to suspend mode.

Anyone help me?

Thanks in advance.

Simon.
