PROBLEM: Successful failure notification making messages to be re sended

Hi Kannelers,

I'm testing Kannel 1.1.6 cvs (June, 6) with Red Hat 7.3.  The SMSC protocol
in use is SMPP 3.4.

I realized that every time Kannel successfuly notify my Application that
messages hadn't been delivery to SMSC (escape %d = 16) it write a new line
in store-file, so every notification of a message not sent increases the
store-file.

The actual problem is when I restart Kannel.  When it happens, Kannel resend
all those messages written in store file which in my point of view shouldn't
happen because my Application looked after those messages when it had
received the original DLR.

What am I doing for work-around?  Renaming the store-file each time Kannel
is being restarted.

Is there anything I have to do?

Many thanks.
