Hi Dennis,

Thanks for your anwser. I know what is error 109. My problem is that "it's not suppose to happen" as far as I can see in my code.

Most of my datas modifications are made by INSERT INTO who is not suppose to lock a file more than a fraction of second. At only one place in my code I use TABLEUPDATE() and my buffering is set to 2.

So As I can't find de bug I try to look at some other possibilities.
